Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627708, here are decompositions:

  • 59 + 31627649 = 31627708
  • 107 + 31627601 = 31627708
  • 131 + 31627577 = 31627708
  • 149 + 31627559 = 31627708
  • 197 + 31627511 = 31627708
  • 317 + 31627391 = 31627708
  • 389 + 31627319 = 31627708
  • 419 + 31627289 = 31627708

Showing the first eight; more decompositions exist.
