Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471978, here are decompositions:

  • 19 + 471959 = 471978
  • 29 + 471949 = 471978
  • 47 + 471931 = 471978
  • 71 + 471907 = 471978
  • 107 + 471871 = 471978
  • 131 + 471847 = 471978
  • 137 + 471841 = 471978
  • 197 + 471781 = 471978

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 471,978 and was likely granted around 1891.

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

Position in π

The digit sequence 471978 first appears in π at position 135,711 of the decimal expansion (the 135,711ordinal-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.
