Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612820, here are decompositions:

23 + 33612797 = 33612820
113 + 33612707 = 33612820
149 + 33612671 = 33612820
239 + 33612581 = 33612820
383 + 33612437 = 33612820
389 + 33612431 = 33612820
491 + 33612329 = 33612820
587 + 33612233 = 33612820

Showing the first eight; more decompositions exist.
