Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621538, here are decompositions:

47 + 33621491 = 33621538
101 + 33621437 = 33621538
131 + 33621407 = 33621538
149 + 33621389 = 33621538
227 + 33621311 = 33621538
239 + 33621299 = 33621538
389 + 33621149 = 33621538
491 + 33621047 = 33621538

Showing the first eight; more decompositions exist.
