Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542072, here are decompositions:

  • 19 + 542053 = 542072
  • 73 + 541999 = 542072
  • 79 + 541993 = 542072
  • 241 + 541831 = 542072
  • 313 + 541759 = 542072
  • 373 + 541699 = 542072
  • 379 + 541693 = 542072
  • 523 + 541549 = 542072

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 542,072 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 542072 first appears in π at position 363,121 of the decimal expansion (the 363,121ordinal-suffix:st 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.
