Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581442, here are decompositions:

5 + 33581437 = 33581442
29 + 33581413 = 33581442
31 + 33581411 = 33581442
61 + 33581381 = 33581442
113 + 33581329 = 33581442
151 + 33581291 = 33581442
163 + 33581279 = 33581442
179 + 33581263 = 33581442

Showing the first eight; more decompositions exist.
