Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500244, here are decompositions:

  • 3 + 2147500241 = 2147500244
  • 61 + 2147500183 = 2147500244
  • 67 + 2147500177 = 2147500244
  • 151 + 2147500093 = 2147500244
  • 163 + 2147500081 = 2147500244
  • 181 + 2147500063 = 2147500244
  • 283 + 2147499961 = 2147500244
  • 541 + 2147499703 = 2147500244

Showing the first eight; more decompositions exist.
