Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498078, here are decompositions:

  • 139 + 2147497939 = 2147498078
  • 157 + 2147497921 = 2147498078
  • 307 + 2147497771 = 2147498078
  • 379 + 2147497699 = 2147498078
  • 571 + 2147497507 = 2147498078
  • 619 + 2147497459 = 2147498078
  • 631 + 2147497447 = 2147498078
  • 757 + 2147497321 = 2147498078

Showing the first eight; more decompositions exist.
