Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513228, here are decompositions:

31 + 33513197 = 33513228
41 + 33513187 = 33513228
61 + 33513167 = 33513228
101 + 33513127 = 33513228
127 + 33513101 = 33513228
131 + 33513097 = 33513228
241 + 33512987 = 33513228
251 + 33512977 = 33513228

Showing the first eight; more decompositions exist.
