Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626780, here are decompositions:

7 + 33626773 = 33626780
37 + 33626743 = 33626780
139 + 33626641 = 33626780
157 + 33626623 = 33626780
199 + 33626581 = 33626780
223 + 33626557 = 33626780
277 + 33626503 = 33626780
283 + 33626497 = 33626780

Showing the first eight; more decompositions exist.
