Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557786, here are decompositions:

19 + 33557767 = 33557786
37 + 33557749 = 33557786
79 + 33557707 = 33557786
103 + 33557683 = 33557786
277 + 33557509 = 33557786
373 + 33557413 = 33557786
463 + 33557323 = 33557786
643 + 33557143 = 33557786

Showing the first eight; more decompositions exist.
