Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497862, here are decompositions:

  • 163 + 2147497699 = 2147497862
  • 199 + 2147497663 = 2147497862
  • 373 + 2147497489 = 2147497862
  • 541 + 2147497321 = 2147497862
  • 619 + 2147497243 = 2147497862
  • 661 + 2147497201 = 2147497862
  • 823 + 2147497039 = 2147497862
  • 883 + 2147496979 = 2147497862

Showing the first eight; more decompositions exist.
