Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449076, here are decompositions:

5 + 31449071 = 31449076
23 + 31449053 = 31449076
47 + 31449029 = 31449076
59 + 31449017 = 31449076
89 + 31448987 = 31449076
167 + 31448909 = 31449076
173 + 31448903 = 31449076
179 + 31448897 = 31449076

Showing the first eight; more decompositions exist.
