Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499922, here are decompositions:

23 + 31499899 = 31499922
29 + 31499893 = 31499922
59 + 31499863 = 31499922
79 + 31499843 = 31499922
89 + 31499833 = 31499922
191 + 31499731 = 31499922
211 + 31499711 = 31499922
263 + 31499659 = 31499922

Showing the first eight; more decompositions exist.
