Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497186, here are decompositions:

  • 53 + 2147497133 = 2147497186
  • 167 + 2147497019 = 2147497186
  • 269 + 2147496917 = 2147497186
  • 347 + 2147496839 = 2147497186
  • 479 + 2147496707 = 2147497186
  • 557 + 2147496629 = 2147497186
  • 563 + 2147496623 = 2147497186
  • 617 + 2147496569 = 2147497186

Showing the first eight; more decompositions exist.
