Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581516, here are decompositions:

79 + 33581437 = 33581516
103 + 33581413 = 33581516
229 + 33581287 = 33581516
307 + 33581209 = 33581516
523 + 33580993 = 33581516
607 + 33580909 = 33581516
613 + 33580903 = 33581516
739 + 33580777 = 33581516

Showing the first eight; more decompositions exist.
