Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581678, here are decompositions:

7 + 33581671 = 33581678
61 + 33581617 = 33581678
79 + 33581599 = 33581678
157 + 33581521 = 33581678
241 + 33581437 = 33581678
349 + 33581329 = 33581678
379 + 33581299 = 33581678
397 + 33581281 = 33581678

Showing the first eight; more decompositions exist.
