Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496306, here are decompositions:

13 + 31496293 = 31496306
43 + 31496263 = 31496306
97 + 31496209 = 31496306
223 + 31496083 = 31496306
409 + 31495897 = 31496306
487 + 31495819 = 31496306
577 + 31495729 = 31496306
613 + 31495693 = 31496306

Showing the first eight; more decompositions exist.
