Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495368, here are decompositions:

7 + 31495361 = 31495368
11 + 31495357 = 31495368
17 + 31495351 = 31495368
127 + 31495241 = 31495368
181 + 31495187 = 31495368
197 + 31495171 = 31495368
211 + 31495157 = 31495368
251 + 31495117 = 31495368

Showing the first eight; more decompositions exist.
