Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626640, here are decompositions:

17 + 33626623 = 33626640
29 + 33626611 = 33626640
43 + 33626597 = 33626640
59 + 33626581 = 33626640
83 + 33626557 = 33626640
97 + 33626543 = 33626640
137 + 33626503 = 33626640
163 + 33626477 = 33626640

Showing the first eight; more decompositions exist.
