Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581154, here are decompositions:

7 + 33581147 = 33581154
23 + 33581131 = 33581154
31 + 33581123 = 33581154
37 + 33581117 = 33581154
67 + 33581087 = 33581154
127 + 33581027 = 33581154
163 + 33580991 = 33581154
197 + 33580957 = 33581154

Showing the first eight; more decompositions exist.
