Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539402, here are decompositions:

  • 13 + 539389 = 539402
  • 79 + 539323 = 539402
  • 109 + 539293 = 539402
  • 313 + 539089 = 539402
  • 463 + 538939 = 539402
  • 601 + 538801 = 539402
  • 613 + 538789 = 539402
  • 631 + 538771 = 539402

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 539,402 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 539402 first appears in π at position 810,238 of the decimal expansion (the 810,238ordinal-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.
