Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481900, here are decompositions:

  • 17 + 481883 = 481900
  • 53 + 481847 = 481900
  • 113 + 481787 = 481900
  • 131 + 481769 = 481900
  • 149 + 481751 = 481900
  • 179 + 481721 = 481900
  • 227 + 481673 = 481900
  • 233 + 481667 = 481900

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 481,900 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 481900 first appears in π at position 24,282 of the decimal expansion (the 24,282ordinal-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.
