Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989816, here are decompositions:

  • 13 + 989803 = 989816
  • 19 + 989797 = 989816
  • 67 + 989749 = 989816
  • 73 + 989743 = 989816
  • 97 + 989719 = 989816
  • 193 + 989623 = 989816
  • 283 + 989533 = 989816
  • 337 + 989479 = 989816

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 989,816 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 989816 first appears in π at position 144,722 of the decimal expansion (the 144,722ordinal-suffix:nd 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.
