Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495050, here are decompositions:

7 + 31495043 = 31495050
31 + 31495019 = 31495050
47 + 31495003 = 31495050
71 + 31494979 = 31495050
101 + 31494949 = 31495050
107 + 31494943 = 31495050
113 + 31494937 = 31495050
127 + 31494923 = 31495050

Showing the first eight; more decompositions exist.
