Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987802, here are decompositions:

  • 5 + 987797 = 987802
  • 89 + 987713 = 987802
  • 269 + 987533 = 987802
  • 293 + 987509 = 987802
  • 311 + 987491 = 987802
  • 419 + 987383 = 987802
  • 449 + 987353 = 987802
  • 503 + 987299 = 987802

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 987,802 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 987802 first appears in π at position 341,249 of the decimal expansion (the 341,249ordinal-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.
