Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500122, here are decompositions:

  • 11 + 2147500111 = 2147500122
  • 29 + 2147500093 = 2147500122
  • 41 + 2147500081 = 2147500122
  • 59 + 2147500063 = 2147500122
  • 73 + 2147500049 = 2147500122
  • 199 + 2147499923 = 2147500122
  • 239 + 2147499883 = 2147500122
  • 281 + 2147499841 = 2147500122

Showing the first eight; more decompositions exist.
