Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625840, here are decompositions:

  • 23 + 33625817 = 33625840
  • 71 + 33625769 = 33625840
  • 89 + 33625751 = 33625840
  • 173 + 33625667 = 33625840
  • 179 + 33625661 = 33625840
  • 239 + 33625601 = 33625840
  • 293 + 33625547 = 33625840
  • 389 + 33625451 = 33625840

Showing the first eight; more decompositions exist.
