Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448862, here are decompositions:

23 + 31448839 = 31448862
41 + 31448821 = 31448862
59 + 31448803 = 31448862
149 + 31448713 = 31448862
163 + 31448699 = 31448862
223 + 31448639 = 31448862
241 + 31448621 = 31448862
281 + 31448581 = 31448862

Showing the first eight; more decompositions exist.
