Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147496880, here are decompositions:

  • 17 + 2147496863 = 2147496880
  • 41 + 2147496839 = 2147496880
  • 101 + 2147496779 = 2147496880
  • 149 + 2147496731 = 2147496880
  • 167 + 2147496713 = 2147496880
  • 173 + 2147496707 = 2147496880
  • 227 + 2147496653 = 2147496880
  • 251 + 2147496629 = 2147496880

Showing the first eight; more decompositions exist.
