Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496022, here are decompositions:

11 + 31496011 = 31496022
43 + 31495979 = 31496022
73 + 31495949 = 31496022
101 + 31495921 = 31496022
163 + 31495859 = 31496022
269 + 31495753 = 31496022
281 + 31495741 = 31496022
293 + 31495729 = 31496022

Showing the first eight; more decompositions exist.
