Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471780, here are decompositions:

  • 11 + 471769 = 471780
  • 31 + 471749 = 471780
  • 59 + 471721 = 471780
  • 61 + 471719 = 471780
  • 83 + 471697 = 471780
  • 97 + 471683 = 471780
  • 103 + 471677 = 471780
  • 107 + 471673 = 471780

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 471,780 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 471780 first appears in π at position 377,829 of the decimal expansion (the 377,829ordinal-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.
