Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497838, here are decompositions:

  • 67 + 2147497771 = 2147497838
  • 139 + 2147497699 = 2147497838
  • 331 + 2147497507 = 2147497838
  • 349 + 2147497489 = 2147497838
  • 379 + 2147497459 = 2147497838
  • 601 + 2147497237 = 2147497838
  • 757 + 2147497081 = 2147497838
  • 859 + 2147496979 = 2147497838

Showing the first eight; more decompositions exist.
