Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481808, here are decompositions:

  • 7 + 481801 = 481808
  • 109 + 481699 = 481808
  • 127 + 481681 = 481808
  • 157 + 481651 = 481808
  • 277 + 481531 = 481808
  • 307 + 481501 = 481808
  • 421 + 481387 = 481808
  • 577 + 481231 = 481808

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 481,808 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 481808 first appears in π at position 576,708 of the decimal expansion (the 576,708ordinal-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.
