Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621904, here are decompositions:

  • 3 + 33621901 = 33621904
  • 23 + 33621881 = 33621904
  • 47 + 33621857 = 33621904
  • 191 + 33621713 = 33621904
  • 293 + 33621611 = 33621904
  • 311 + 33621593 = 33621904
  • 431 + 33621473 = 33621904
  • 467 + 33621437 = 33621904

Showing the first eight; more decompositions exist.
