Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531600, here are decompositions:

  • 13 + 33531587 = 33531600
  • 23 + 33531577 = 33531600
  • 41 + 33531559 = 33531600
  • 59 + 33531541 = 33531600
  • 73 + 33531527 = 33531600
  • 97 + 33531503 = 33531600
  • 101 + 33531499 = 33531600
  • 127 + 33531473 = 33531600

Showing the first eight; more decompositions exist.
