Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513290, here are decompositions:

43 + 33513247 = 33513290
103 + 33513187 = 33513290
127 + 33513163 = 33513290
157 + 33513133 = 33513290
163 + 33513127 = 33513290
193 + 33513097 = 33513290
313 + 33512977 = 33513290
331 + 33512959 = 33513290

Showing the first eight; more decompositions exist.
