Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619638, here are decompositions:

11 + 33619627 = 33619638
61 + 33619577 = 33619638
97 + 33619541 = 33619638
109 + 33619529 = 33619638
127 + 33619511 = 33619638
167 + 33619471 = 33619638
197 + 33619441 = 33619638
211 + 33619427 = 33619638

Showing the first eight; more decompositions exist.
