Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497684, here are decompositions:

  • 23 + 2147497661 = 2147497684
  • 113 + 2147497571 = 2147497684
  • 191 + 2147497493 = 2147497684
  • 281 + 2147497403 = 2147497684
  • 641 + 2147497043 = 2147497684
  • 743 + 2147496941 = 2147497684
  • 821 + 2147496863 = 2147497684
  • 953 + 2147496731 = 2147497684

Showing the first eight; more decompositions exist.
