Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756428, here are decompositions:

  • 47 + 8756381 = 8756428
  • 71 + 8756357 = 8756428
  • 227 + 8756201 = 8756428
  • 269 + 8756159 = 8756428
  • 311 + 8756117 = 8756428
  • 389 + 8756039 = 8756428
  • 419 + 8756009 = 8756428
  • 431 + 8755997 = 8756428

Showing the first eight; more decompositions exist.
