Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531360, here are decompositions:

7 + 33531353 = 33531360
11 + 33531349 = 33531360
13 + 33531347 = 33531360
41 + 33531319 = 33531360
61 + 33531299 = 33531360
113 + 33531247 = 33531360
127 + 33531233 = 33531360
131 + 33531229 = 33531360

Showing the first eight; more decompositions exist.
