Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27240, here are decompositions:

  • 29 + 27211 = 27240
  • 43 + 27197 = 27240
  • 61 + 27179 = 27240
  • 97 + 27143 = 27240
  • 113 + 27127 = 27240
  • 131 + 27109 = 27240
  • 137 + 27103 = 27240
  • 149 + 27091 = 27240

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27240 first appears in π at position 135,324 of the decimal expansion (the 135,324ordinal-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.
