Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545272, here are decompositions:

61 + 31545211 = 31545272
181 + 31545091 = 31545272
211 + 31545061 = 31545272
223 + 31545049 = 31545272
271 + 31545001 = 31545272
331 + 31544941 = 31545272
349 + 31544923 = 31545272
373 + 31544899 = 31545272

Showing the first eight; more decompositions exist.
