Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621286, here are decompositions:

3 + 33621283 = 33621286
53 + 33621233 = 33621286
113 + 33621173 = 33621286
137 + 33621149 = 33621286
173 + 33621113 = 33621286
239 + 33621047 = 33621286
359 + 33620927 = 33621286
467 + 33620819 = 33621286

Showing the first eight; more decompositions exist.
