Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581646, here are decompositions:

29 + 33581617 = 33581646
47 + 33581599 = 33581646
73 + 33581573 = 33581646
233 + 33581413 = 33581646
317 + 33581329 = 33581646
347 + 33581299 = 33581646
349 + 33581297 = 33581646
359 + 33581287 = 33581646

Showing the first eight; more decompositions exist.
