Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660728, here are decompositions:

  • 5 + 8660723 = 8660728
  • 29 + 8660699 = 8660728
  • 47 + 8660681 = 8660728
  • 71 + 8660657 = 8660728
  • 149 + 8660579 = 8660728
  • 191 + 8660537 = 8660728
  • 347 + 8660381 = 8660728
  • 359 + 8660369 = 8660728

Showing the first eight; more decompositions exist.
