Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542418, here are decompositions:

  • 17 + 542401 = 542418
  • 47 + 542371 = 542418
  • 137 + 542281 = 542418
  • 157 + 542261 = 542418
  • 167 + 542251 = 542418
  • 181 + 542237 = 542418
  • 199 + 542219 = 542418
  • 211 + 542207 = 542418

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 542,418 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 542418 first appears in π at position 308,343 of the decimal expansion (the 308,343ordinal-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.
