Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463128, here are decompositions:

5 + 31463123 = 31463128
29 + 31463099 = 31463128
41 + 31463087 = 31463128
149 + 31462979 = 31463128
197 + 31462931 = 31463128
227 + 31462901 = 31463128
239 + 31462889 = 31463128
251 + 31462877 = 31463128

Showing the first eight; more decompositions exist.
