Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496112, here are decompositions:

13 + 31496099 = 31496112
29 + 31496083 = 31496112
71 + 31496041 = 31496112
101 + 31496011 = 31496112
163 + 31495949 = 31496112
191 + 31495921 = 31496112
233 + 31495879 = 31496112
293 + 31495819 = 31496112

Showing the first eight; more decompositions exist.
