Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987634, here are decompositions:

  • 3 + 987631 = 987634
  • 41 + 987593 = 987634
  • 47 + 987587 = 987634
  • 101 + 987533 = 987634
  • 251 + 987383 = 987634
  • 281 + 987353 = 987634
  • 383 + 987251 = 987634
  • 443 + 987191 = 987634

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 987,634 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 987634 first appears in π at position 86,845 of the decimal expansion (the 86,845ordinal-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.
