Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496826, here are decompositions:

7 + 31496819 = 31496826
17 + 31496809 = 31496826
43 + 31496783 = 31496826
47 + 31496779 = 31496826
107 + 31496719 = 31496826
149 + 31496677 = 31496826
157 + 31496669 = 31496826
227 + 31496599 = 31496826

Showing the first eight; more decompositions exist.
