Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463010, here are decompositions:

31 + 31462979 = 31463010
41 + 31462969 = 31463010
79 + 31462931 = 31463010
101 + 31462909 = 31463010
109 + 31462901 = 31463010
113 + 31462897 = 31463010
179 + 31462831 = 31463010
199 + 31462811 = 31463010

Showing the first eight; more decompositions exist.
