Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507640, here are decompositions:

17 + 33507623 = 33507640
29 + 33507611 = 33507640
41 + 33507599 = 33507640
137 + 33507503 = 33507640
197 + 33507443 = 33507640
227 + 33507413 = 33507640
233 + 33507407 = 33507640
239 + 33507401 = 33507640

Showing the first eight; more decompositions exist.
