Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608840, here are decompositions:

103 + 33608737 = 33608840
157 + 33608683 = 33608840
193 + 33608647 = 33608840
211 + 33608629 = 33608840
229 + 33608611 = 33608840
271 + 33608569 = 33608840
277 + 33608563 = 33608840
313 + 33608527 = 33608840

Showing the first eight; more decompositions exist.
