Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627048, here are decompositions:

  • 41 + 31627007 = 31627048
  • 71 + 31626977 = 31627048
  • 149 + 31626899 = 31627048
  • 179 + 31626869 = 31627048
  • 191 + 31626857 = 31627048
  • 251 + 31626797 = 31627048
  • 281 + 31626767 = 31627048
  • 359 + 31626689 = 31627048

Showing the first eight; more decompositions exist.
