Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555640, here are decompositions:

11 + 33555629 = 33555640
23 + 33555617 = 33555640
29 + 33555611 = 33555640
113 + 33555527 = 33555640
179 + 33555461 = 33555640
191 + 33555449 = 33555640
257 + 33555383 = 33555640
263 + 33555377 = 33555640

Showing the first eight; more decompositions exist.
