Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623442, here are decompositions:

23 + 33623419 = 33623442
53 + 33623389 = 33623442
71 + 33623371 = 33623442
79 + 33623363 = 33623442
89 + 33623353 = 33623442
101 + 33623341 = 33623442
113 + 33623329 = 33623442
199 + 33623243 = 33623442

Showing the first eight; more decompositions exist.
