Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448922, here are decompositions:

13 + 31448909 = 31448922
19 + 31448903 = 31448922
23 + 31448899 = 31448922
31 + 31448891 = 31448922
59 + 31448863 = 31448922
83 + 31448839 = 31448922
101 + 31448821 = 31448922
181 + 31448741 = 31448922

Showing the first eight; more decompositions exist.
