Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989940, here are decompositions:

  • 11 + 989929 = 989940
  • 19 + 989921 = 989940
  • 23 + 989917 = 989940
  • 31 + 989909 = 989940
  • 53 + 989887 = 989940
  • 67 + 989873 = 989940
  • 71 + 989869 = 989940
  • 101 + 989839 = 989940

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 989,940 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 989940 first appears in π at position 187,983 of the decimal expansion (the 187,983ordinal-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.
