Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613880, here are decompositions:

19 + 33613861 = 33613880
31 + 33613849 = 33613880
37 + 33613843 = 33613880
73 + 33613807 = 33613880
199 + 33613681 = 33613880
283 + 33613597 = 33613880
331 + 33613549 = 33613880
397 + 33613483 = 33613880

Showing the first eight; more decompositions exist.
