Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516380, here are decompositions:

31 + 33516349 = 33516380
43 + 33516337 = 33516380
61 + 33516319 = 33516380
97 + 33516283 = 33516380
103 + 33516277 = 33516380
127 + 33516253 = 33516380
199 + 33516181 = 33516380
223 + 33516157 = 33516380

Showing the first eight; more decompositions exist.
