Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27430, here are decompositions:

  • 3 + 27427 = 27430
  • 23 + 27407 = 27430
  • 101 + 27329 = 27430
  • 131 + 27299 = 27430
  • 149 + 27281 = 27430
  • 191 + 27239 = 27430
  • 233 + 27197 = 27430
  • 239 + 27191 = 27430

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27430 first appears in π at position 112,792 of the decimal expansion (the 112,792ordinal-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.
