Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542388, here are decompositions:

  • 17 + 542371 = 542388
  • 89 + 542299 = 542388
  • 107 + 542281 = 542388
  • 127 + 542261 = 542388
  • 137 + 542251 = 542388
  • 151 + 542237 = 542388
  • 181 + 542207 = 542388
  • 191 + 542197 = 542388

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 542,388 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 542388 first appears in π at position 241,557 of the decimal expansion (the 241,557ordinal-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.
