Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29872, here are decompositions:

  • 5 + 29867 = 29872
  • 53 + 29819 = 29872
  • 83 + 29789 = 29872
  • 113 + 29759 = 29872
  • 131 + 29741 = 29872
  • 149 + 29723 = 29872
  • 239 + 29633 = 29872
  • 389 + 29483 = 29872

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29872 first appears in π at position 37,984 of the decimal expansion (the 37,984ordinal-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.
