Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495366, here are decompositions:

5 + 31495361 = 31495366
167 + 31495199 = 31495366
179 + 31495187 = 31495366
257 + 31495109 = 31495366
347 + 31495019 = 31495366
443 + 31494923 = 31495366
479 + 31494887 = 31495366
557 + 31494809 = 31495366

Showing the first eight; more decompositions exist.
