Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561538, here are decompositions:

5 + 33561533 = 33561538
11 + 33561527 = 33561538
149 + 33561389 = 33561538
251 + 33561287 = 33561538
347 + 33561191 = 33561538
449 + 33561089 = 33561538
587 + 33560951 = 33561538
599 + 33560939 = 33561538

Showing the first eight; more decompositions exist.
