Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691646, here are decompositions:

  • 3 + 8691643 = 8691646
  • 23 + 8691623 = 8691646
  • 53 + 8691593 = 8691646
  • 59 + 8691587 = 8691646
  • 137 + 8691509 = 8691646
  • 149 + 8691497 = 8691646
  • 167 + 8691479 = 8691646
  • 233 + 8691413 = 8691646

Showing the first eight; more decompositions exist.
