Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613826, here are decompositions:

7 + 31613819 = 31613826
19 + 31613807 = 31613826
29 + 31613797 = 31613826
43 + 31613783 = 31613826
107 + 31613719 = 31613826
109 + 31613717 = 31613826
157 + 31613669 = 31613826
197 + 31613629 = 31613826

Showing the first eight; more decompositions exist.
