Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987724, here are decompositions:

  • 11 + 987713 = 987724
  • 131 + 987593 = 987724
  • 137 + 987587 = 987724
  • 191 + 987533 = 987724
  • 233 + 987491 = 987724
  • 251 + 987473 = 987724
  • 431 + 987293 = 987724
  • 641 + 987083 = 987724

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 987,724 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 987724 first appears in π at position 589,628 of the decimal expansion (the 589,628ordinal-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.
