Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498342, here are decompositions:

  • 163 + 2147498179 = 2147498342
  • 421 + 2147497921 = 2147498342
  • 571 + 2147497771 = 2147498342
  • 643 + 2147497699 = 2147498342
  • 853 + 2147497489 = 2147498342
  • 883 + 2147497459 = 2147498342
  • 1021 + 2147497321 = 2147498342
  • 1201 + 2147497141 = 2147498342

Showing the first eight; more decompositions exist.
