Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463148, here are decompositions:

11 + 31463137 = 31463148
61 + 31463087 = 31463148
71 + 31463077 = 31463148
179 + 31462969 = 31463148
239 + 31462909 = 31463148
251 + 31462897 = 31463148
271 + 31462877 = 31463148
317 + 31462831 = 31463148

Showing the first eight; more decompositions exist.
