Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531622, here are decompositions:

  • 43 + 31531579 = 31531622
  • 139 + 31531483 = 31531622
  • 151 + 31531471 = 31531622
  • 223 + 31531399 = 31531622
  • 349 + 31531273 = 31531622
  • 373 + 31531249 = 31531622
  • 523 + 31531099 = 31531622
  • 643 + 31530979 = 31531622

Showing the first eight; more decompositions exist.
