Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33616642, here are decompositions:

5 + 33616637 = 33616642
23 + 33616619 = 33616642
239 + 33616403 = 33616642
251 + 33616391 = 33616642
401 + 33616241 = 33616642
431 + 33616211 = 33616642
443 + 33616199 = 33616642
593 + 33616049 = 33616642

Showing the first eight; more decompositions exist.
