Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561388, here are decompositions:

101 + 33561287 = 33561388
191 + 33561197 = 33561388
197 + 33561191 = 33561388
227 + 33561161 = 33561388
389 + 33560999 = 33561388
449 + 33560939 = 33561388
647 + 33560741 = 33561388
659 + 33560729 = 33561388

Showing the first eight; more decompositions exist.
