Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463082, here are decompositions:

5 + 31463077 = 31463082
19 + 31463063 = 31463082
59 + 31463023 = 31463082
103 + 31462979 = 31463082
113 + 31462969 = 31463082
149 + 31462933 = 31463082
151 + 31462931 = 31463082
173 + 31462909 = 31463082

Showing the first eight; more decompositions exist.
