Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39748, here are decompositions:

  • 29 + 39719 = 39748
  • 89 + 39659 = 39748
  • 167 + 39581 = 39748
  • 179 + 39569 = 39748
  • 197 + 39551 = 39748
  • 227 + 39521 = 39748
  • 239 + 39509 = 39748
  • 389 + 39359 = 39748

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39748 first appears in π at position 2,978 of the decimal expansion (the 2,978ordinal-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.
