Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496190, here are decompositions:

17 + 31496173 = 31496190
29 + 31496161 = 31496190
67 + 31496123 = 31496190
71 + 31496119 = 31496190
107 + 31496083 = 31496190
149 + 31496041 = 31496190
163 + 31496027 = 31496190
179 + 31496011 = 31496190

Showing the first eight; more decompositions exist.
