Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495246, here are decompositions:

5 + 31495241 = 31495246
47 + 31495199 = 31495246
59 + 31495187 = 31495246
89 + 31495157 = 31495246
137 + 31495109 = 31495246
227 + 31495019 = 31495246
359 + 31494887 = 31495246
479 + 31494767 = 31495246

Showing the first eight; more decompositions exist.
