Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507540, here are decompositions:

37 + 33507503 = 33507540
97 + 33507443 = 33507540
127 + 33507413 = 33507540
139 + 33507401 = 33507540
163 + 33507377 = 33507540
181 + 33507359 = 33507540
193 + 33507347 = 33507540
233 + 33507307 = 33507540

Showing the first eight; more decompositions exist.
