Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531978, here are decompositions:

  • 31 + 33531947 = 33531978
  • 47 + 33531931 = 33531978
  • 59 + 33531919 = 33531978
  • 89 + 33531889 = 33531978
  • 101 + 33531877 = 33531978
  • 131 + 33531847 = 33531978
  • 197 + 33531781 = 33531978
  • 229 + 33531749 = 33531978

Showing the first eight; more decompositions exist.
