Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509778, here are decompositions:

37 + 33509741 = 33509778
97 + 33509681 = 33509778
131 + 33509647 = 33509778
251 + 33509527 = 33509778
277 + 33509501 = 33509778
317 + 33509461 = 33509778
349 + 33509429 = 33509778
389 + 33509389 = 33509778

Showing the first eight; more decompositions exist.
