Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512780, here are decompositions:

109 + 33512671 = 33512780
127 + 33512653 = 33512780
139 + 33512641 = 33512780
151 + 33512629 = 33512780
163 + 33512617 = 33512780
211 + 33512569 = 33512780
277 + 33512503 = 33512780
313 + 33512467 = 33512780

Showing the first eight; more decompositions exist.
