Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500154, here are decompositions:

  • 31 + 2147500123 = 2147500154
  • 43 + 2147500111 = 2147500154
  • 61 + 2147500093 = 2147500154
  • 73 + 2147500081 = 2147500154
  • 157 + 2147499997 = 2147500154
  • 193 + 2147499961 = 2147500154
  • 271 + 2147499883 = 2147500154
  • 313 + 2147499841 = 2147500154

Showing the first eight; more decompositions exist.
