Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495362, here are decompositions:

5 + 31495357 = 31495362
11 + 31495351 = 31495362
29 + 31495333 = 31495362
89 + 31495273 = 31495362
149 + 31495213 = 31495362
163 + 31495199 = 31495362
191 + 31495171 = 31495362
359 + 31495003 = 31495362

Showing the first eight; more decompositions exist.
