Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747438, here are decompositions:

  • 19 + 8747419 = 8747438
  • 31 + 8747407 = 8747438
  • 109 + 8747329 = 8747438
  • 181 + 8747257 = 8747438
  • 367 + 8747071 = 8747438
  • 397 + 8747041 = 8747438
  • 439 + 8746999 = 8747438
  • 499 + 8746939 = 8747438

Showing the first eight; more decompositions exist.
