Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521678, here are decompositions:

31 + 33521647 = 33521678
139 + 33521539 = 33521678
241 + 33521437 = 33521678
277 + 33521401 = 33521678
457 + 33521221 = 33521678
499 + 33521179 = 33521678
691 + 33520987 = 33521678
739 + 33520939 = 33521678

Showing the first eight; more decompositions exist.
