Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561238, here are decompositions:

41 + 33561197 = 33561238
47 + 33561191 = 33561238
149 + 33561089 = 33561238
239 + 33560999 = 33561238
509 + 33560729 = 33561238
521 + 33560717 = 33561238
587 + 33560651 = 33561238
677 + 33560561 = 33561238

Showing the first eight; more decompositions exist.
