Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496172, here are decompositions:

11 + 31496161 = 31496172
31 + 31496141 = 31496172
53 + 31496119 = 31496172
73 + 31496099 = 31496172
89 + 31496083 = 31496172
131 + 31496041 = 31496172
193 + 31495979 = 31496172
223 + 31495949 = 31496172

Showing the first eight; more decompositions exist.
