Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481890, here are decompositions:

  • 7 + 481883 = 481890
  • 11 + 481879 = 481890
  • 23 + 481867 = 481890
  • 29 + 481861 = 481890
  • 41 + 481849 = 481890
  • 43 + 481847 = 481890
  • 47 + 481843 = 481890
  • 53 + 481837 = 481890

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 481,890 and was likely granted around 1892.

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

Position in π

The digit sequence 481890 first appears in π at position 952,562 of the decimal expansion (the 952,562ordinal-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.
