Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982640, here are decompositions:

  • 7 + 982633 = 982640
  • 19 + 982621 = 982640
  • 37 + 982603 = 982640
  • 67 + 982573 = 982640
  • 151 + 982489 = 982640
  • 277 + 982363 = 982640
  • 367 + 982273 = 982640
  • 409 + 982231 = 982640

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 982,640 and was likely granted around 1910.

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

Position in π

The digit sequence 982640 first appears in π at position 304,165 of the decimal expansion (the 304,165ordinal-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.
