Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542156, here are decompositions:

  • 3 + 542153 = 542156
  • 7 + 542149 = 542156
  • 37 + 542119 = 542156
  • 73 + 542083 = 542156
  • 103 + 542053 = 542156
  • 157 + 541999 = 542156
  • 163 + 541993 = 542156
  • 229 + 541927 = 542156

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 542,156 and was likely granted around 1895.

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

Position in π

The digit sequence 542156 first appears in π at position 847,829 of the decimal expansion (the 847,829ordinal-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.
