Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27400, here are decompositions:

  • 3 + 27397 = 27400
  • 71 + 27329 = 27400
  • 101 + 27299 = 27400
  • 257 + 27143 = 27400
  • 293 + 27107 = 27400
  • 383 + 27017 = 27400
  • 389 + 27011 = 27400
  • 419 + 26981 = 27400

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27400 first appears in π at position 45,381 of the decimal expansion (the 45,381ordinal-suffix:st 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.
