Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495610, here are decompositions:

7 + 31495603 = 31495610
19 + 31495591 = 31495610
109 + 31495501 = 31495610
163 + 31495447 = 31495610
193 + 31495417 = 31495610
277 + 31495333 = 31495610
337 + 31495273 = 31495610
397 + 31495213 = 31495610

Showing the first eight; more decompositions exist.
