Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495032, here are decompositions:

13 + 31495019 = 31495032
29 + 31495003 = 31495032
53 + 31494979 = 31495032
83 + 31494949 = 31495032
89 + 31494943 = 31495032
109 + 31494923 = 31495032
113 + 31494919 = 31495032
223 + 31494809 = 31495032

Showing the first eight; more decompositions exist.
