Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448906, here are decompositions:

3 + 31448903 = 31448906
7 + 31448899 = 31448906
43 + 31448863 = 31448906
67 + 31448839 = 31448906
103 + 31448803 = 31448906
193 + 31448713 = 31448906
199 + 31448707 = 31448906
373 + 31448533 = 31448906

Showing the first eight; more decompositions exist.
