Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33492390, here are decompositions:

11 + 33492379 = 33492390
17 + 33492373 = 33492390
53 + 33492337 = 33492390
67 + 33492323 = 33492390
79 + 33492311 = 33492390
167 + 33492223 = 33492390
193 + 33492197 = 33492390
251 + 33492139 = 33492390

Showing the first eight; more decompositions exist.
