Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27408, here are decompositions:

  • 11 + 27397 = 27408
  • 41 + 27367 = 27408
  • 47 + 27361 = 27408
  • 71 + 27337 = 27408
  • 79 + 27329 = 27408
  • 109 + 27299 = 27408
  • 127 + 27281 = 27408
  • 131 + 27277 = 27408

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27408 first appears in π at position 299,528 of the decimal expansion (the 299,528ordinal-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.
