Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485218, here are decompositions:

59 + 33485159 = 33485218
167 + 33485051 = 33485218
197 + 33485021 = 33485218
251 + 33484967 = 33485218
311 + 33484907 = 33485218
449 + 33484769 = 33485218
467 + 33484751 = 33485218
509 + 33484709 = 33485218

Showing the first eight; more decompositions exist.
