Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458108, here are decompositions:

47 + 31458061 = 31458108
109 + 31457999 = 31458108
139 + 31457969 = 31458108
179 + 31457929 = 31458108
197 + 31457911 = 31458108
239 + 31457869 = 31458108
251 + 31457857 = 31458108
277 + 31457831 = 31458108

Showing the first eight; more decompositions exist.
