Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555652, here are decompositions:

  • 19 + 31555633 = 31555652
  • 103 + 31555549 = 31555652
  • 109 + 31555543 = 31555652
  • 223 + 31555429 = 31555652
  • 409 + 31555243 = 31555652
  • 571 + 31555081 = 31555652
  • 631 + 31555021 = 31555652
  • 691 + 31554961 = 31555652

Showing the first eight; more decompositions exist.
