Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463028, here are decompositions:

5 + 31463023 = 31463028
59 + 31462969 = 31463028
97 + 31462931 = 31463028
127 + 31462901 = 31463028
131 + 31462897 = 31463028
139 + 31462889 = 31463028
151 + 31462877 = 31463028
197 + 31462831 = 31463028

Showing the first eight; more decompositions exist.
