Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672470, here are decompositions:

  • 29 + 8672441 = 8672470
  • 41 + 8672429 = 8672470
  • 47 + 8672423 = 8672470
  • 83 + 8672387 = 8672470
  • 89 + 8672381 = 8672470
  • 137 + 8672333 = 8672470
  • 173 + 8672297 = 8672470
  • 197 + 8672273 = 8672470

Showing the first eight; more decompositions exist.
