Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147818, here are decompositions:

  • 7 + 147811 = 147818
  • 19 + 147799 = 147818
  • 31 + 147787 = 147818
  • 79 + 147739 = 147818
  • 109 + 147709 = 147818
  • 157 + 147661 = 147818
  • 211 + 147607 = 147818
  • 271 + 147547 = 147818

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 147,818 and was likely granted around 1873.

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

Position in π

The digit sequence 147818 first appears in π at position 169,404 of the decimal expansion (the 169,404ordinal-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.
