Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508478, here are decompositions:

7 + 33508471 = 33508478
61 + 33508417 = 33508478
139 + 33508339 = 33508478
331 + 33508147 = 33508478
541 + 33507937 = 33508478
571 + 33507907 = 33508478
727 + 33507751 = 33508478
877 + 33507601 = 33508478

Showing the first eight; more decompositions exist.
