Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531390, here are decompositions:

37 + 33531353 = 33531390
41 + 33531349 = 33531390
43 + 33531347 = 33531390
71 + 33531319 = 33531390
107 + 33531283 = 33531390
157 + 33531233 = 33531390
223 + 33531167 = 33531390
293 + 33531097 = 33531390

Showing the first eight; more decompositions exist.
