Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27458, here are decompositions:

  • 31 + 27427 = 27458
  • 61 + 27397 = 27458
  • 97 + 27361 = 27458
  • 181 + 27277 = 27458
  • 199 + 27259 = 27458
  • 331 + 27127 = 27458
  • 349 + 27109 = 27458
  • 367 + 27091 = 27458

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27458 first appears in π at position 24,434 of the decimal expansion (the 24,434ordinal-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.
