Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530388, here are decompositions:

  • 5 + 31530383 = 31530388
  • 11 + 31530377 = 31530388
  • 41 + 31530347 = 31530388
  • 47 + 31530341 = 31530388
  • 191 + 31530197 = 31530388
  • 359 + 31530029 = 31530388
  • 419 + 31529969 = 31530388
  • 569 + 31529819 = 31530388

Showing the first eight; more decompositions exist.
