Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581788, here are decompositions:

47 + 33581741 = 33581788
101 + 33581687 = 33581788
167 + 33581621 = 33581788
347 + 33581441 = 33581788
467 + 33581321 = 33581788
491 + 33581297 = 33581788
509 + 33581279 = 33581788
521 + 33581267 = 33581788

Showing the first eight; more decompositions exist.
