Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527164, here are decompositions:

7 + 31527157 = 31527164
13 + 31527151 = 31527164
211 + 31526953 = 31527164
223 + 31526941 = 31527164
271 + 31526893 = 31527164
283 + 31526881 = 31527164
373 + 31526791 = 31527164
433 + 31526731 = 31527164

Showing the first eight; more decompositions exist.
