Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939800, here are decompositions:

  • 7 + 939793 = 939800
  • 31 + 939769 = 939800
  • 61 + 939739 = 939800
  • 139 + 939661 = 939800
  • 151 + 939649 = 939800
  • 313 + 939487 = 939800
  • 331 + 939469 = 939800
  • 349 + 939451 = 939800

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 939,800 and was likely granted around 1909.

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

Position in π

The digit sequence 939800 first appears in π at position 251,602 of the decimal expansion (the 251,602ordinal-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.
