Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639802, here are decompositions:

  • 5 + 8639797 = 8639802
  • 23 + 8639779 = 8639802
  • 29 + 8639773 = 8639802
  • 53 + 8639749 = 8639802
  • 89 + 8639713 = 8639802
  • 139 + 8639663 = 8639802
  • 163 + 8639639 = 8639802
  • 211 + 8639591 = 8639802

Showing the first eight; more decompositions exist.
