Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29142, here are decompositions:

  • 5 + 29137 = 29142
  • 11 + 29131 = 29142
  • 13 + 29129 = 29142
  • 19 + 29123 = 29142
  • 41 + 29101 = 29142
  • 79 + 29063 = 29142
  • 83 + 29059 = 29142
  • 109 + 29033 = 29142

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29142 first appears in π at position 46,632 of the decimal expansion (the 46,632ordinal-suffix:nd 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.
