Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630180, here are decompositions:

  • 3 + 8630177 = 8630180
  • 7 + 8630173 = 8630180
  • 61 + 8630119 = 8630180
  • 67 + 8630113 = 8630180
  • 109 + 8630071 = 8630180
  • 151 + 8630029 = 8630180
  • 199 + 8629981 = 8630180
  • 271 + 8629909 = 8630180

Showing the first eight; more decompositions exist.
