Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621830, here are decompositions:

7 + 33621823 = 33621830
43 + 33621787 = 33621830
79 + 33621751 = 33621830
103 + 33621727 = 33621830
139 + 33621691 = 33621830
157 + 33621673 = 33621830
181 + 33621649 = 33621830
271 + 33621559 = 33621830

Showing the first eight; more decompositions exist.
