Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39388, here are decompositions:

  • 5 + 39383 = 39388
  • 17 + 39371 = 39388
  • 29 + 39359 = 39388
  • 47 + 39341 = 39388
  • 71 + 39317 = 39388
  • 137 + 39251 = 39388
  • 149 + 39239 = 39388
  • 179 + 39209 = 39388

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39388 first appears in π at position 40,329 of the decimal expansion (the 40,329ordinal-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.
