Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472840, here are decompositions:

  • 17 + 33472823 = 33472840
  • 53 + 33472787 = 33472840
  • 251 + 33472589 = 33472840
  • 263 + 33472577 = 33472840
  • 347 + 33472493 = 33472840
  • 353 + 33472487 = 33472840
  • 509 + 33472331 = 33472840
  • 617 + 33472223 = 33472840

Showing the first eight; more decompositions exist.
