Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500218, here are decompositions:

  • 41 + 2147500177 = 2147500218
  • 79 + 2147500139 = 2147500218
  • 107 + 2147500111 = 2147500218
  • 137 + 2147500081 = 2147500218
  • 211 + 2147500007 = 2147500218
  • 229 + 2147499989 = 2147500218
  • 257 + 2147499961 = 2147500218
  • 389 + 2147499829 = 2147500218

Showing the first eight; more decompositions exist.
