Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39572, here are decompositions:

  • 3 + 39569 = 39572
  • 31 + 39541 = 39572
  • 61 + 39511 = 39572
  • 73 + 39499 = 39572
  • 163 + 39409 = 39572
  • 199 + 39373 = 39572
  • 229 + 39343 = 39572
  • 271 + 39301 = 39572

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39572 first appears in π at position 214,177 of the decimal expansion (the 214,177ordinal-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.
