Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527464, here are decompositions:

211 + 31527253 = 31527464
271 + 31527193 = 31527464
307 + 31527157 = 31527464
313 + 31527151 = 31527464
523 + 31526941 = 31527464
571 + 31526893 = 31527464
601 + 31526863 = 31527464
673 + 31526791 = 31527464

Showing the first eight; more decompositions exist.
