Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495996, here are decompositions:

17 + 31495979 = 31495996
47 + 31495949 = 31495996
137 + 31495859 = 31495996
149 + 31495847 = 31495996
239 + 31495757 = 31495996
263 + 31495733 = 31495996
479 + 31495517 = 31495996
503 + 31495493 = 31495996

Showing the first eight; more decompositions exist.
