Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623086, here are decompositions:

127 + 31622959 = 31623086
139 + 31622947 = 31623086
163 + 31622923 = 31623086
193 + 31622893 = 31623086
223 + 31622863 = 31623086
277 + 31622809 = 31623086
283 + 31622803 = 31623086
307 + 31622779 = 31623086

Showing the first eight; more decompositions exist.
