Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621474, here are decompositions:

37 + 33621437 = 33621474
67 + 33621407 = 33621474
113 + 33621361 = 33621474
163 + 33621311 = 33621474
191 + 33621283 = 33621474
223 + 33621251 = 33621474
241 + 33621233 = 33621474
311 + 33621163 = 33621474

Showing the first eight; more decompositions exist.
