Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448850, here are decompositions:

11 + 31448839 = 31448850
29 + 31448821 = 31448850
47 + 31448803 = 31448850
109 + 31448741 = 31448850
131 + 31448719 = 31448850
137 + 31448713 = 31448850
151 + 31448699 = 31448850
157 + 31448693 = 31448850

Showing the first eight; more decompositions exist.
