Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448844, here are decompositions:

5 + 31448839 = 31448844
23 + 31448821 = 31448844
41 + 31448803 = 31448844
103 + 31448741 = 31448844
127 + 31448717 = 31448844
131 + 31448713 = 31448844
137 + 31448707 = 31448844
151 + 31448693 = 31448844

Showing the first eight; more decompositions exist.
