Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25504, here are decompositions:

  • 41 + 25463 = 25504
  • 47 + 25457 = 25504
  • 113 + 25391 = 25504
  • 131 + 25373 = 25504
  • 137 + 25367 = 25504
  • 197 + 25307 = 25504
  • 251 + 25253 = 25504
  • 257 + 25247 = 25504

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25504 first appears in π at position 198,110 of the decimal expansion (the 198,110ordinal-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.
