Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624820, here are decompositions:

  • 3 + 33624817 = 33624820
  • 17 + 33624803 = 33624820
  • 29 + 33624791 = 33624820
  • 113 + 33624707 = 33624820
  • 137 + 33624683 = 33624820
  • 179 + 33624641 = 33624820
  • 191 + 33624629 = 33624820
  • 233 + 33624587 = 33624820

Showing the first eight; more decompositions exist.
