Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635128, here are decompositions:

  • 11 + 8635117 = 8635128
  • 41 + 8635087 = 8635128
  • 67 + 8635061 = 8635128
  • 71 + 8635057 = 8635128
  • 79 + 8635049 = 8635128
  • 107 + 8635021 = 8635128
  • 157 + 8634971 = 8635128
  • 167 + 8634961 = 8635128

Showing the first eight; more decompositions exist.
