Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626390, here are decompositions:

97 + 33626293 = 33626390
103 + 33626287 = 33626390
211 + 33626179 = 33626390
283 + 33626107 = 33626390
313 + 33626077 = 33626390
379 + 33626011 = 33626390
541 + 33625849 = 33626390
547 + 33625843 = 33626390

Showing the first eight; more decompositions exist.
