Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538642, here are decompositions:

3 + 33538639 = 33538642
23 + 33538619 = 33538642
41 + 33538601 = 33538642
131 + 33538511 = 33538642
173 + 33538469 = 33538642
239 + 33538403 = 33538642
383 + 33538259 = 33538642
419 + 33538223 = 33538642

Showing the first eight; more decompositions exist.
