Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523292, here are decompositions:

13 + 31523279 = 31523292
41 + 31523251 = 31523292
61 + 31523231 = 31523292
71 + 31523221 = 31523292
83 + 31523209 = 31523292
131 + 31523161 = 31523292
149 + 31523143 = 31523292
173 + 31523119 = 31523292

Showing the first eight; more decompositions exist.
