Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29686, here are decompositions:

  • 3 + 29683 = 29686
  • 17 + 29669 = 29686
  • 23 + 29663 = 29686
  • 53 + 29633 = 29686
  • 113 + 29573 = 29686
  • 149 + 29537 = 29686
  • 233 + 29453 = 29686
  • 257 + 29429 = 29686

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29686 first appears in π at position 43,650 of the decimal expansion (the 43,650ordinal-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.
