Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463080, here are decompositions:

3 + 31463077 = 31463080
17 + 31463063 = 31463080
101 + 31462979 = 31463080
149 + 31462931 = 31463080
179 + 31462901 = 31463080
191 + 31462889 = 31463080
269 + 31462811 = 31463080
431 + 31462649 = 31463080

Showing the first eight; more decompositions exist.
