Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542420, here are decompositions:

  • 19 + 542401 = 542420
  • 97 + 542323 = 542420
  • 127 + 542293 = 542420
  • 139 + 542281 = 542420
  • 157 + 542263 = 542420
  • 223 + 542197 = 542420
  • 271 + 542149 = 542420
  • 337 + 542083 = 542420

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 542,420 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 542420 first appears in π at position 330,063 of the decimal expansion (the 330,063ordinal-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.
