Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581812, here are decompositions:

71 + 33581741 = 33581812
191 + 33581621 = 33581812
239 + 33581573 = 33581812
401 + 33581411 = 33581812
419 + 33581393 = 33581812
431 + 33581381 = 33581812
461 + 33581351 = 33581812
491 + 33581321 = 33581812

Showing the first eight; more decompositions exist.
