Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728802, here are decompositions:

  • 139 + 8728663 = 8728802
  • 193 + 8728609 = 8728802
  • 211 + 8728591 = 8728802
  • 223 + 8728579 = 8728802
  • 331 + 8728471 = 8728802
  • 421 + 8728381 = 8728802
  • 499 + 8728303 = 8728802
  • 541 + 8728261 = 8728802

Showing the first eight; more decompositions exist.
