Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497550, here are decompositions:

  • 43 + 2147497507 = 2147497550
  • 61 + 2147497489 = 2147497550
  • 103 + 2147497447 = 2147497550
  • 139 + 2147497411 = 2147497550
  • 157 + 2147497393 = 2147497550
  • 229 + 2147497321 = 2147497550
  • 307 + 2147497243 = 2147497550
  • 313 + 2147497237 = 2147497550

Showing the first eight; more decompositions exist.
