Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449036, here are decompositions:

7 + 31449029 = 31449036
19 + 31449017 = 31449036
127 + 31448909 = 31449036
137 + 31448899 = 31449036
139 + 31448897 = 31449036
173 + 31448863 = 31449036
197 + 31448839 = 31449036
233 + 31448803 = 31449036

Showing the first eight; more decompositions exist.
