Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707472, here are decompositions:

  • 43 + 8707429 = 8707472
  • 79 + 8707393 = 8707472
  • 139 + 8707333 = 8707472
  • 199 + 8707273 = 8707472
  • 283 + 8707189 = 8707472
  • 313 + 8707159 = 8707472
  • 349 + 8707123 = 8707472
  • 379 + 8707093 = 8707472

Showing the first eight; more decompositions exist.
