Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497648, here are decompositions:

  • 89 + 2147497559 = 2147497648
  • 167 + 2147497481 = 2147497648
  • 677 + 2147496971 = 2147497648
  • 809 + 2147496839 = 2147497648
  • 941 + 2147496707 = 2147497648
  • 1019 + 2147496629 = 2147497648
  • 1091 + 2147496557 = 2147497648
  • 1097 + 2147496551 = 2147497648

Showing the first eight; more decompositions exist.
