Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523194, here are decompositions:

83 + 31523111 = 31523194
113 + 31523081 = 31523194
167 + 31523027 = 31523194
173 + 31523021 = 31523194
191 + 31523003 = 31523194
233 + 31522961 = 31523194
257 + 31522937 = 31523194
293 + 31522901 = 31523194

Showing the first eight; more decompositions exist.
