Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522844, here are decompositions:

  • 97 + 31522747 = 31522844
  • 127 + 31522717 = 31522844
  • 151 + 31522693 = 31522844
  • 181 + 31522663 = 31522844
  • 211 + 31522633 = 31522844
  • 433 + 31522411 = 31522844
  • 487 + 31522357 = 31522844
  • 547 + 31522297 = 31522844

Showing the first eight; more decompositions exist.
