Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496148, here are decompositions:

7 + 31496141 = 31496148
29 + 31496119 = 31496148
107 + 31496041 = 31496148
137 + 31496011 = 31496148
199 + 31495949 = 31496148
227 + 31495921 = 31496148
251 + 31495897 = 31496148
269 + 31495879 = 31496148

Showing the first eight; more decompositions exist.
