Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147496886, here are decompositions:

  • 23 + 2147496863 = 2147496886
  • 47 + 2147496839 = 2147496886
  • 107 + 2147496779 = 2147496886
  • 173 + 2147496713 = 2147496886
  • 179 + 2147496707 = 2147496886
  • 233 + 2147496653 = 2147496886
  • 257 + 2147496629 = 2147496886
  • 263 + 2147496623 = 2147496886

Showing the first eight; more decompositions exist.
