Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581782, here are decompositions:

41 + 33581741 = 33581782
89 + 33581693 = 33581782
389 + 33581393 = 33581782
401 + 33581381 = 33581782
431 + 33581351 = 33581782
461 + 33581321 = 33581782
491 + 33581291 = 33581782
503 + 33581279 = 33581782

Showing the first eight; more decompositions exist.
