Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495336, here are decompositions:

3 + 31495333 = 31495336
137 + 31495199 = 31495336
149 + 31495187 = 31495336
179 + 31495157 = 31495336
227 + 31495109 = 31495336
293 + 31495043 = 31495336
317 + 31495019 = 31495336
449 + 31494887 = 31495336

Showing the first eight; more decompositions exist.
