Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627608, here are decompositions:

  • 7 + 31627601 = 31627608
  • 31 + 31627577 = 31627608
  • 41 + 31627567 = 31627608
  • 71 + 31627537 = 31627608
  • 97 + 31627511 = 31627608
  • 107 + 31627501 = 31627608
  • 197 + 31627411 = 31627608
  • 251 + 31627357 = 31627608

Showing the first eight; more decompositions exist.
