Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487782, here are decompositions:

11 + 33487771 = 33487782
23 + 33487759 = 33487782
101 + 33487681 = 33487782
131 + 33487651 = 33487782
151 + 33487631 = 33487782
191 + 33487591 = 33487782
239 + 33487543 = 33487782
269 + 33487513 = 33487782

Showing the first eight; more decompositions exist.
