Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497370, here are decompositions:

  • 127 + 2147497243 = 2147497370
  • 229 + 2147497141 = 2147497370
  • 331 + 2147497039 = 2147497370
  • 373 + 2147496997 = 2147497370
  • 409 + 2147496961 = 2147497370
  • 433 + 2147496937 = 2147497370
  • 523 + 2147496847 = 2147497370
  • 541 + 2147496829 = 2147497370

Showing the first eight; more decompositions exist.
