Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719646, here are decompositions:

  • 43 + 8719603 = 8719646
  • 73 + 8719573 = 8719646
  • 79 + 8719567 = 8719646
  • 97 + 8719549 = 8719646
  • 127 + 8719519 = 8719646
  • 163 + 8719483 = 8719646
  • 373 + 8719273 = 8719646
  • 433 + 8719213 = 8719646

Showing the first eight; more decompositions exist.
