Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587218, here are decompositions:

107 + 33587111 = 33587218
167 + 33587051 = 33587218
179 + 33587039 = 33587218
227 + 33586991 = 33587218
281 + 33586937 = 33587218
311 + 33586907 = 33587218
389 + 33586829 = 33587218
647 + 33586571 = 33587218

Showing the first eight; more decompositions exist.
