Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526556, here are decompositions:

  • 23 + 31526533 = 31526556
  • 29 + 31526527 = 31526556
  • 53 + 31526503 = 31526556
  • 59 + 31526497 = 31526556
  • 67 + 31526489 = 31526556
  • 79 + 31526477 = 31526556
  • 137 + 31526419 = 31526556
  • 167 + 31526389 = 31526556

Showing the first eight; more decompositions exist.
