Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561490, here are decompositions:

101 + 33561389 = 33561490
227 + 33561263 = 33561490
293 + 33561197 = 33561490
317 + 33561173 = 33561490
401 + 33561089 = 33561490
467 + 33561023 = 33561490
491 + 33560999 = 33561490
647 + 33560843 = 33561490

Showing the first eight; more decompositions exist.
