Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561478, here are decompositions:

89 + 33561389 = 33561478
191 + 33561287 = 33561478
281 + 33561197 = 33561478
317 + 33561161 = 33561478
389 + 33561089 = 33561478
479 + 33560999 = 33561478
761 + 33560717 = 33561478
827 + 33560651 = 33561478

Showing the first eight; more decompositions exist.
