Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587130, here are decompositions:

19 + 33587111 = 33587130
41 + 33587089 = 33587130
79 + 33587051 = 33587130
139 + 33586991 = 33587130
173 + 33586957 = 33587130
191 + 33586939 = 33587130
193 + 33586937 = 33587130
223 + 33586907 = 33587130

Showing the first eight; more decompositions exist.
