Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521372, here are decompositions:

151 + 33521221 = 33521372
193 + 33521179 = 33521372
433 + 33520939 = 33521372
571 + 33520801 = 33521372
613 + 33520759 = 33521372
691 + 33520681 = 33521372
751 + 33520621 = 33521372
769 + 33520603 = 33521372

Showing the first eight; more decompositions exist.
