Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449030, here are decompositions:

13 + 31449017 = 31449030
43 + 31448987 = 31449030
127 + 31448903 = 31449030
131 + 31448899 = 31449030
139 + 31448891 = 31449030
167 + 31448863 = 31449030
191 + 31448839 = 31449030
227 + 31448803 = 31449030

Showing the first eight; more decompositions exist.
