Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495206, here are decompositions:

7 + 31495199 = 31495206
19 + 31495187 = 31495206
53 + 31495153 = 31495206
59 + 31495147 = 31495206
89 + 31495117 = 31495206
97 + 31495109 = 31495206
163 + 31495043 = 31495206
227 + 31494979 = 31495206

Showing the first eight; more decompositions exist.
