Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621368, here are decompositions:

  • 29 + 8621339 = 8621368
  • 59 + 8621309 = 8621368
  • 131 + 8621237 = 8621368
  • 167 + 8621201 = 8621368
  • 179 + 8621189 = 8621368
  • 281 + 8621087 = 8621368
  • 317 + 8621051 = 8621368
  • 359 + 8621009 = 8621368

Showing the first eight; more decompositions exist.
