Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542020, here are decompositions:

  • 29 + 541991 = 542020
  • 53 + 541967 = 542020
  • 131 + 541889 = 542020
  • 239 + 541781 = 542020
  • 257 + 541763 = 542020
  • 293 + 541727 = 542020
  • 359 + 541661 = 542020
  • 389 + 541631 = 542020

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 542,020 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 542020 first appears in π at position 152,063 of the decimal expansion (the 152,063ordinal-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.
