Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448882, here are decompositions:

19 + 31448863 = 31448882
43 + 31448839 = 31448882
61 + 31448821 = 31448882
79 + 31448803 = 31448882
163 + 31448719 = 31448882
331 + 31448551 = 31448882
349 + 31448533 = 31448882
433 + 31448449 = 31448882

Showing the first eight; more decompositions exist.
