Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978942, here are decompositions:

  • 11 + 978931 = 978942
  • 59 + 978883 = 978942
  • 71 + 978871 = 978942
  • 79 + 978863 = 978942
  • 89 + 978853 = 978942
  • 103 + 978839 = 978942
  • 193 + 978749 = 978942
  • 199 + 978743 = 978942

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 978,942 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 978942 first appears in π at position 956,901 of the decimal expansion (the 956,901ordinal-suffix:st 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.
