Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521786, here are decompositions:

3 + 33521783 = 33521786
73 + 33521713 = 33521786
97 + 33521689 = 33521786
139 + 33521647 = 33521786
157 + 33521629 = 33521786
163 + 33521623 = 33521786
349 + 33521437 = 33521786
607 + 33521179 = 33521786

Showing the first eight; more decompositions exist.
