Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463118, here are decompositions:

19 + 31463099 = 31463118
31 + 31463087 = 31463118
41 + 31463077 = 31463118
139 + 31462979 = 31463118
149 + 31462969 = 31463118
229 + 31462889 = 31463118
241 + 31462877 = 31463118
307 + 31462811 = 31463118

Showing the first eight; more decompositions exist.
