Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521618, here are decompositions:

79 + 33521539 = 33521618
157 + 33521461 = 33521618
181 + 33521437 = 33521618
397 + 33521221 = 33521618
439 + 33521179 = 33521618
631 + 33520987 = 33521618
727 + 33520891 = 33521618
859 + 33520759 = 33521618

Showing the first eight; more decompositions exist.
