Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557378, here are decompositions:

37 + 33557341 = 33557378
61 + 33557317 = 33557378
181 + 33557197 = 33557378
277 + 33557101 = 33557378
331 + 33557047 = 33557378
367 + 33557011 = 33557378
409 + 33556969 = 33557378
457 + 33556921 = 33557378

Showing the first eight; more decompositions exist.
