Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495106, here are decompositions:

43 + 31495063 = 31495106
103 + 31495003 = 31495106
127 + 31494979 = 31495106
157 + 31494949 = 31495106
163 + 31494943 = 31495106
199 + 31494907 = 31495106
337 + 31494769 = 31495106
463 + 31494643 = 31495106

Showing the first eight; more decompositions exist.
