Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496838, here are decompositions:

11 + 31496827 = 31496838
19 + 31496819 = 31496838
29 + 31496809 = 31496838
47 + 31496791 = 31496838
59 + 31496779 = 31496838
97 + 31496741 = 31496838
167 + 31496671 = 31496838
227 + 31496611 = 31496838

Showing the first eight; more decompositions exist.
