Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448950, here are decompositions:

41 + 31448909 = 31448950
47 + 31448903 = 31448950
53 + 31448897 = 31448950
59 + 31448891 = 31448950
233 + 31448717 = 31448950
251 + 31448699 = 31448950
257 + 31448693 = 31448950
311 + 31448639 = 31448950

Showing the first eight; more decompositions exist.
