Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580188, here are decompositions:

17 + 33580171 = 33580188
29 + 33580159 = 33580188
67 + 33580121 = 33580188
97 + 33580091 = 33580188
107 + 33580081 = 33580188
127 + 33580061 = 33580188
149 + 33580039 = 33580188
157 + 33580031 = 33580188

Showing the first eight; more decompositions exist.
