Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507628, here are decompositions:

5 + 33507623 = 33507628
17 + 33507611 = 33507628
29 + 33507599 = 33507628
227 + 33507401 = 33507628
251 + 33507377 = 33507628
269 + 33507359 = 33507628
281 + 33507347 = 33507628
461 + 33507167 = 33507628

Showing the first eight; more decompositions exist.
