Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581618, here are decompositions:

19 + 33581599 = 33581618
97 + 33581521 = 33581618
127 + 33581491 = 33581618
181 + 33581437 = 33581618
331 + 33581287 = 33581618
337 + 33581281 = 33581618
397 + 33581221 = 33581618
409 + 33581209 = 33581618

Showing the first eight; more decompositions exist.
