Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531840, here are decompositions:

  • 47 + 33531793 = 33531840
  • 59 + 33531781 = 33531840
  • 103 + 33531737 = 33531840
  • 179 + 33531661 = 33531840
  • 227 + 33531613 = 33531840
  • 229 + 33531611 = 33531840
  • 263 + 33531577 = 33531840
  • 281 + 33531559 = 33531840

Showing the first eight; more decompositions exist.
