Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39242, here are decompositions:

  • 3 + 39239 = 39242
  • 13 + 39229 = 39242
  • 43 + 39199 = 39242
  • 61 + 39181 = 39242
  • 79 + 39163 = 39242
  • 103 + 39139 = 39242
  • 109 + 39133 = 39242
  • 139 + 39103 = 39242

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39242 first appears in π at position 35,740 of the decimal expansion (the 35,740ordinal-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.
