Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448826, here are decompositions:

5 + 31448821 = 31448826
23 + 31448803 = 31448826
107 + 31448719 = 31448826
109 + 31448717 = 31448826
113 + 31448713 = 31448826
127 + 31448699 = 31448826
179 + 31448647 = 31448826
223 + 31448603 = 31448826

Showing the first eight; more decompositions exist.
