Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526574, here are decompositions:

  • 11 + 31526563 = 31526574
  • 41 + 31526533 = 31526574
  • 47 + 31526527 = 31526574
  • 71 + 31526503 = 31526574
  • 97 + 31526477 = 31526574
  • 151 + 31526423 = 31526574
  • 223 + 31526351 = 31526574
  • 257 + 31526317 = 31526574

Showing the first eight; more decompositions exist.
