Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617840, here are decompositions:

7 + 33617833 = 33617840
37 + 33617803 = 33617840
43 + 33617797 = 33617840
73 + 33617767 = 33617840
79 + 33617761 = 33617840
211 + 33617629 = 33617840
229 + 33617611 = 33617840
241 + 33617599 = 33617840

Showing the first eight; more decompositions exist.
