Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531256, here are decompositions:

23 + 33531233 = 33531256
89 + 33531167 = 33531256
173 + 33531083 = 33531256
179 + 33531077 = 33531256
197 + 33531059 = 33531256
257 + 33530999 = 33531256
419 + 33530837 = 33531256
443 + 33530813 = 33531256

Showing the first eight; more decompositions exist.
