Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481780, here are decompositions:

  • 11 + 481769 = 481780
  • 29 + 481751 = 481780
  • 59 + 481721 = 481780
  • 83 + 481697 = 481780
  • 107 + 481673 = 481780
  • 113 + 481667 = 481780
  • 191 + 481589 = 481780
  • 311 + 481469 = 481780

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 481,780 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 481780 first appears in π at position 362,532 of the decimal expansion (the 362,532ordinal-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.
