Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496216, here are decompositions:

7 + 31496209 = 31496216
43 + 31496173 = 31496216
97 + 31496119 = 31496216
337 + 31495879 = 31496216
397 + 31495819 = 31496216
463 + 31495753 = 31496216
487 + 31495729 = 31496216
523 + 31495693 = 31496216

Showing the first eight; more decompositions exist.
