Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495166, here are decompositions:

13 + 31495153 = 31495166
19 + 31495147 = 31495166
103 + 31495063 = 31495166
163 + 31495003 = 31495166
223 + 31494943 = 31495166
229 + 31494937 = 31495166
349 + 31494817 = 31495166
397 + 31494769 = 31495166

Showing the first eight; more decompositions exist.
