Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618742, here are decompositions:

5 + 33618737 = 33618742
23 + 33618719 = 33618742
71 + 33618671 = 33618742
251 + 33618491 = 33618742
383 + 33618359 = 33618742
419 + 33618323 = 33618742
491 + 33618251 = 33618742
569 + 33618173 = 33618742

Showing the first eight; more decompositions exist.
