Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490022, here are decompositions:

23 + 31489999 = 31490022
59 + 31489963 = 31490022
73 + 31489949 = 31490022
79 + 31489943 = 31490022
103 + 31489919 = 31490022
139 + 31489883 = 31490022
149 + 31489873 = 31490022
181 + 31489841 = 31490022

Showing the first eight; more decompositions exist.
