Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621986, here are decompositions:

127 + 33621859 = 33621986
163 + 33621823 = 33621986
199 + 33621787 = 33621986
313 + 33621673 = 33621986
337 + 33621649 = 33621986
577 + 33621409 = 33621986
733 + 33621253 = 33621986
823 + 33621163 = 33621986

Showing the first eight; more decompositions exist.
