Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600552, here are decompositions:

  • 3 + 31600549 = 31600552
  • 23 + 31600529 = 31600552
  • 29 + 31600523 = 31600552
  • 41 + 31600511 = 31600552
  • 59 + 31600493 = 31600552
  • 101 + 31600451 = 31600552
  • 131 + 31600421 = 31600552
  • 233 + 31600319 = 31600552

Showing the first eight; more decompositions exist.
