Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28484, here are decompositions:

  • 7 + 28477 = 28484
  • 37 + 28447 = 28484
  • 73 + 28411 = 28484
  • 97 + 28387 = 28484
  • 283 + 28201 = 28484
  • 373 + 28111 = 28484
  • 397 + 28087 = 28484
  • 433 + 28051 = 28484

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28484 first appears in π at position 180,736 of the decimal expansion (the 180,736ordinal-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.
