Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702228, here are decompositions:

  • 79 + 8702149 = 8702228
  • 97 + 8702131 = 8702228
  • 229 + 8701999 = 8702228
  • 277 + 8701951 = 8702228
  • 307 + 8701921 = 8702228
  • 439 + 8701789 = 8702228
  • 487 + 8701741 = 8702228
  • 499 + 8701729 = 8702228

Showing the first eight; more decompositions exist.
