Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190800, here are decompositions:

  • 7 + 190793 = 190800
  • 13 + 190787 = 190800
  • 17 + 190783 = 190800
  • 31 + 190769 = 190800
  • 37 + 190763 = 190800
  • 41 + 190759 = 190800
  • 47 + 190753 = 190800
  • 83 + 190717 = 190800

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 190,800 and was likely granted around 1875.

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

Position in π

The digit sequence 190800 first appears in π at position 47,004 of the decimal expansion (the 47,004ordinal-suffix:th 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.
