Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123798, here are decompositions:

  • 7 + 123791 = 123798
  • 11 + 123787 = 123798
  • 41 + 123757 = 123798
  • 61 + 123737 = 123798
  • 67 + 123731 = 123798
  • 71 + 123727 = 123798
  • 79 + 123719 = 123798
  • 97 + 123701 = 123798

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 123,798 and was likely granted around 1871.

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

Position in π

The digit sequence 123798 first appears in π at position 478,943 of the decimal expansion (the 478,943ordinal-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.
