Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521390, here are decompositions:

211 + 33521179 = 33521390
307 + 33521083 = 33521390
499 + 33520891 = 33521390
547 + 33520843 = 33521390
577 + 33520813 = 33521390
607 + 33520783 = 33521390
613 + 33520777 = 33521390
631 + 33520759 = 33521390

Showing the first eight; more decompositions exist.
