Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495046, here are decompositions:

3 + 31495043 = 31495046
43 + 31495003 = 31495046
67 + 31494979 = 31495046
97 + 31494949 = 31495046
103 + 31494943 = 31495046
109 + 31494937 = 31495046
127 + 31494919 = 31495046
139 + 31494907 = 31495046

Showing the first eight; more decompositions exist.
