Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581432, here are decompositions:

19 + 33581413 = 33581432
103 + 33581329 = 33581432
151 + 33581281 = 33581432
211 + 33581221 = 33581432
223 + 33581209 = 33581432
421 + 33581011 = 33581432
439 + 33580993 = 33581432
523 + 33580909 = 33581432

Showing the first eight; more decompositions exist.
