Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002028, here are decompositions:

  • 11 + 1002017 = 1002028
  • 47 + 1001981 = 1002028
  • 197 + 1001831 = 1002028
  • 227 + 1001801 = 1002028
  • 359 + 1001669 = 1002028
  • 389 + 1001639 = 1002028
  • 479 + 1001549 = 1002028
  • 569 + 1001459 = 1002028

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,002,028 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1002028 first appears in π at position 869,925 of the decimal expansion (the 869,925ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
