Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531482, here are decompositions:

11 + 31531471 = 31531482
29 + 31531453 = 31531482
61 + 31531421 = 31531482
79 + 31531403 = 31531482
83 + 31531399 = 31531482
113 + 31531369 = 31531482
179 + 31531303 = 31531482
181 + 31531301 = 31531482

Showing the first eight; more decompositions exist.
