Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497688, here are decompositions:

  • 181 + 2147497507 = 2147497688
  • 199 + 2147497489 = 2147497688
  • 229 + 2147497459 = 2147497688
  • 241 + 2147497447 = 2147497688
  • 277 + 2147497411 = 2147497688
  • 367 + 2147497321 = 2147497688
  • 487 + 2147497201 = 2147497688
  • 547 + 2147497141 = 2147497688

Showing the first eight; more decompositions exist.
