Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620072, here are decompositions:

  • 3 + 8620069 = 8620072
  • 23 + 8620049 = 8620072
  • 29 + 8620043 = 8620072
  • 179 + 8619893 = 8620072
  • 281 + 8619791 = 8620072
  • 353 + 8619719 = 8620072
  • 359 + 8619713 = 8620072
  • 389 + 8619683 = 8620072

Showing the first eight; more decompositions exist.
