Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581742, here are decompositions:

71 + 33581671 = 33581742
251 + 33581491 = 33581742
331 + 33581411 = 33581742
349 + 33581393 = 33581742
421 + 33581321 = 33581742
443 + 33581299 = 33581742
461 + 33581281 = 33581742
463 + 33581279 = 33581742

Showing the first eight; more decompositions exist.
