Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627192, here are decompositions:

  • 41 + 31627151 = 31627192
  • 59 + 31627133 = 31627192
  • 71 + 31627121 = 31627192
  • 101 + 31627091 = 31627192
  • 293 + 31626899 = 31627192
  • 353 + 31626839 = 31627192
  • 503 + 31626689 = 31627192
  • 659 + 31626533 = 31627192

Showing the first eight; more decompositions exist.
