Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495928, here are decompositions:

7 + 31495921 = 31495928
31 + 31495897 = 31495928
109 + 31495819 = 31495928
127 + 31495801 = 31495928
199 + 31495729 = 31495928
271 + 31495657 = 31495928
337 + 31495591 = 31495928
571 + 31495357 = 31495928

Showing the first eight; more decompositions exist.
