Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724028, here are decompositions:

  • 41 + 8723987 = 8724028
  • 107 + 8723921 = 8724028
  • 149 + 8723879 = 8724028
  • 239 + 8723789 = 8724028
  • 389 + 8723639 = 8724028
  • 419 + 8723609 = 8724028
  • 569 + 8723459 = 8724028
  • 587 + 8723441 = 8724028

Showing the first eight; more decompositions exist.
