Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622986, here are decompositions:

  • 47 + 31622939 = 31622986
  • 53 + 31622933 = 31622986
  • 149 + 31622837 = 31622986
  • 257 + 31622729 = 31622986
  • 293 + 31622693 = 31622986
  • 449 + 31622537 = 31622986
  • 467 + 31622519 = 31622986
  • 557 + 31622429 = 31622986

Showing the first eight; more decompositions exist.
