Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621170, here are decompositions:

7 + 33621163 = 33621170
61 + 33621109 = 33621170
103 + 33621067 = 33621170
139 + 33621031 = 33621170
211 + 33620959 = 33621170
241 + 33620929 = 33621170
313 + 33620857 = 33621170
367 + 33620803 = 33621170

Showing the first eight; more decompositions exist.
