Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607280, here are decompositions:

37 + 33607243 = 33607280
43 + 33607237 = 33607280
67 + 33607213 = 33607280
151 + 33607129 = 33607280
193 + 33607087 = 33607280
199 + 33607081 = 33607280
229 + 33607051 = 33607280
271 + 33607009 = 33607280

Showing the first eight; more decompositions exist.
