Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169800, here are decompositions:

  • 11 + 169789 = 169800
  • 17 + 169783 = 169800
  • 23 + 169777 = 169800
  • 31 + 169769 = 169800
  • 47 + 169753 = 169800
  • 67 + 169733 = 169800
  • 107 + 169693 = 169800
  • 109 + 169691 = 169800

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 169,800 and was likely granted around 1874.

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

Position in π

The digit sequence 169800 first appears in π at position 148,052 of the decimal expansion (the 148,052ordinal-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.
