Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489490, here are decompositions:

59 + 33489431 = 33489490
113 + 33489377 = 33489490
149 + 33489341 = 33489490
197 + 33489293 = 33489490
233 + 33489257 = 33489490
263 + 33489227 = 33489490
269 + 33489221 = 33489490
311 + 33489179 = 33489490

Showing the first eight; more decompositions exist.
