Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39646, here are decompositions:

  • 23 + 39623 = 39646
  • 83 + 39563 = 39646
  • 137 + 39509 = 39646
  • 227 + 39419 = 39646
  • 263 + 39383 = 39646
  • 353 + 39293 = 39646
  • 419 + 39227 = 39646
  • 557 + 39089 = 39646

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39646 first appears in π at position 40,031 of the decimal expansion (the 40,031ordinal-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.
