Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523262, here are decompositions:

11 + 31523251 = 31523262
19 + 31523243 = 31523262
31 + 31523231 = 31523262
41 + 31523221 = 31523262
53 + 31523209 = 31523262
61 + 31523201 = 31523262
101 + 31523161 = 31523262
131 + 31523131 = 31523262

Showing the first eight; more decompositions exist.
