Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512778, here are decompositions:

31 + 33512747 = 33512778
97 + 33512681 = 33512778
107 + 33512671 = 33512778
137 + 33512641 = 33512778
149 + 33512629 = 33512778
199 + 33512579 = 33512778
241 + 33512537 = 33512778
307 + 33512471 = 33512778

Showing the first eight; more decompositions exist.
