Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496312, here are decompositions:

19 + 31496293 = 31496312
103 + 31496209 = 31496312
139 + 31496173 = 31496312
151 + 31496161 = 31496312
193 + 31496119 = 31496312
229 + 31496083 = 31496312
271 + 31496041 = 31496312
433 + 31495879 = 31496312

Showing the first eight; more decompositions exist.
