Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561628, here are decompositions:

17 + 33561611 = 33561628
29 + 33561599 = 33561628
71 + 33561557 = 33561628
101 + 33561527 = 33561628
239 + 33561389 = 33561628
431 + 33561197 = 33561628
467 + 33561161 = 33561628
677 + 33560951 = 33561628

Showing the first eight; more decompositions exist.
