Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522986, here are decompositions:

  • 7 + 31522979 = 31522986
  • 97 + 31522889 = 31522986
  • 113 + 31522873 = 31522986
  • 139 + 31522847 = 31522986
  • 163 + 31522823 = 31522986
  • 239 + 31522747 = 31522986
  • 269 + 31522717 = 31522986
  • 293 + 31522693 = 31522986

Showing the first eight; more decompositions exist.
