Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622980, here are decompositions:

  • 29 + 31622951 = 31622980
  • 41 + 31622939 = 31622980
  • 47 + 31622933 = 31622980
  • 239 + 31622741 = 31622980
  • 251 + 31622729 = 31622980
  • 281 + 31622699 = 31622980
  • 293 + 31622687 = 31622980
  • 317 + 31622663 = 31622980

Showing the first eight; more decompositions exist.
