Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496192, here are decompositions:

19 + 31496173 = 31496192
31 + 31496161 = 31496192
73 + 31496119 = 31496192
109 + 31496083 = 31496192
151 + 31496041 = 31496192
181 + 31496011 = 31496192
271 + 31495921 = 31496192
313 + 31495879 = 31496192

Showing the first eight; more decompositions exist.
