Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29160, here are decompositions:

  • 7 + 29153 = 29160
  • 13 + 29147 = 29160
  • 23 + 29137 = 29160
  • 29 + 29131 = 29160
  • 31 + 29129 = 29160
  • 37 + 29123 = 29160
  • 59 + 29101 = 29160
  • 83 + 29077 = 29160

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29160 first appears in π at position 7,786 of the decimal expansion (the 7,786ordinal-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.
