Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448744, here are decompositions:

3 + 31448741 = 31448744
31 + 31448713 = 31448744
37 + 31448707 = 31448744
97 + 31448647 = 31448744
157 + 31448587 = 31448744
163 + 31448581 = 31448744
193 + 31448551 = 31448744
211 + 31448533 = 31448744

Showing the first eight; more decompositions exist.
