Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626654, here are decompositions:

  • 47 + 31626607 = 31626654
  • 83 + 31626571 = 31626654
  • 97 + 31626557 = 31626654
  • 107 + 31626547 = 31626654
  • 173 + 31626481 = 31626654
  • 193 + 31626461 = 31626654
  • 233 + 31626421 = 31626654
  • 271 + 31626383 = 31626654

Showing the first eight; more decompositions exist.
