Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448856, here are decompositions:

17 + 31448839 = 31448856
53 + 31448803 = 31448856
137 + 31448719 = 31448856
139 + 31448717 = 31448856
149 + 31448707 = 31448856
157 + 31448699 = 31448856
163 + 31448693 = 31448856
269 + 31448587 = 31448856

Showing the first eight; more decompositions exist.
