Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487028, here are decompositions:

  • 7 + 487021 = 487028
  • 37 + 486991 = 487028
  • 79 + 486949 = 487028
  • 211 + 486817 = 487028
  • 271 + 486757 = 487028
  • 307 + 486721 = 487028
  • 331 + 486697 = 487028
  • 349 + 486679 = 487028

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 487,028 and was likely granted around 1892.

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

Position in π

The digit sequence 487028 first appears in π at position 238,371 of the decimal expansion (the 238,371ordinal-suffix:st 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.
