Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542220, here are decompositions:

  • 13 + 542207 = 542220
  • 23 + 542197 = 542220
  • 31 + 542189 = 542220
  • 37 + 542183 = 542220
  • 53 + 542167 = 542220
  • 67 + 542153 = 542220
  • 71 + 542149 = 542220
  • 79 + 542141 = 542220

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 542,220 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 542220 first appears in π at position 98,133 of the decimal expansion (the 98,133ordinal-suffix:rd 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.
