Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581818, here are decompositions:

5 + 33581813 = 33581818
131 + 33581687 = 33581818
197 + 33581621 = 33581818
467 + 33581351 = 33581818
521 + 33581297 = 33581818
701 + 33581117 = 33581818
719 + 33581099 = 33581818
797 + 33581021 = 33581818

Showing the first eight; more decompositions exist.
