Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626920, here are decompositions:

29 + 33626891 = 33626920
59 + 33626861 = 33626920
71 + 33626849 = 33626920
83 + 33626837 = 33626920
101 + 33626819 = 33626920
149 + 33626771 = 33626920
233 + 33626687 = 33626920
281 + 33626639 = 33626920

Showing the first eight; more decompositions exist.
