Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626240, here are decompositions:

3 + 33626237 = 33626240
61 + 33626179 = 33626240
163 + 33626077 = 33626240
229 + 33626011 = 33626240
331 + 33625909 = 33626240
397 + 33625843 = 33626240
409 + 33625831 = 33626240
673 + 33625567 = 33626240

Showing the first eight; more decompositions exist.
