Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555816, here are decompositions:

17 + 33555799 = 33555816
59 + 33555757 = 33555816
79 + 33555737 = 33555816
89 + 33555727 = 33555816
113 + 33555703 = 33555816
137 + 33555679 = 33555816
149 + 33555667 = 33555816
157 + 33555659 = 33555816

Showing the first eight; more decompositions exist.
