Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987022, here are decompositions:

  • 41 + 986981 = 987022
  • 59 + 986963 = 987022
  • 89 + 986933 = 987022
  • 173 + 986849 = 987022
  • 263 + 986759 = 987022
  • 293 + 986729 = 987022
  • 389 + 986633 = 987022
  • 479 + 986543 = 987022

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 987,022 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 987022 first appears in π at position 571,523 of the decimal expansion (the 571,523ordinal-suffix:rd 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.
