Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607640, here are decompositions:

37 + 33607603 = 33607640
67 + 33607573 = 33607640
151 + 33607489 = 33607640
223 + 33607417 = 33607640
229 + 33607411 = 33607640
271 + 33607369 = 33607640
397 + 33607243 = 33607640
607 + 33607033 = 33607640

Showing the first eight; more decompositions exist.
