Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497026, here are decompositions:

  • 19 + 31497007 = 31497026
  • 37 + 31496989 = 31497026
  • 79 + 31496947 = 31497026
  • 109 + 31496917 = 31497026
  • 163 + 31496863 = 31497026
  • 199 + 31496827 = 31497026
  • 307 + 31496719 = 31497026
  • 349 + 31496677 = 31497026

Showing the first eight; more decompositions exist.
