Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621186, here are decompositions:

13 + 33621173 = 33621186
17 + 33621169 = 33621186
23 + 33621163 = 33621186
37 + 33621149 = 33621186
73 + 33621113 = 33621186
103 + 33621083 = 33621186
139 + 33621047 = 33621186
149 + 33621037 = 33621186

Showing the first eight; more decompositions exist.
