Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581642, here are decompositions:

43 + 33581599 = 33581642
151 + 33581491 = 33581642
229 + 33581413 = 33581642
313 + 33581329 = 33581642
379 + 33581263 = 33581642
421 + 33581221 = 33581642
433 + 33581209 = 33581642
631 + 33581011 = 33581642

Showing the first eight; more decompositions exist.
