Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557738, here are decompositions:

7 + 33557731 = 33557738
31 + 33557707 = 33557738
37 + 33557701 = 33557738
229 + 33557509 = 33557738
271 + 33557467 = 33557738
397 + 33557341 = 33557738
421 + 33557317 = 33557738
541 + 33557197 = 33557738

Showing the first eight; more decompositions exist.
