Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497754, here are decompositions:

  • 37 + 2147497717 = 2147497754
  • 307 + 2147497447 = 2147497754
  • 433 + 2147497321 = 2147497754
  • 613 + 2147497141 = 2147497754
  • 673 + 2147497081 = 2147497754
  • 757 + 2147496997 = 2147497754
  • 907 + 2147496847 = 2147497754
  • 937 + 2147496817 = 2147497754

Showing the first eight; more decompositions exist.
