Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557690, here are decompositions:

7 + 33557683 = 33557690
73 + 33557617 = 33557690
181 + 33557509 = 33557690
223 + 33557467 = 33557690
277 + 33557413 = 33557690
349 + 33557341 = 33557690
367 + 33557323 = 33557690
373 + 33557317 = 33557690

Showing the first eight; more decompositions exist.
