Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523482, here are decompositions:

5 + 31523477 = 31523482
41 + 31523441 = 31523482
71 + 31523411 = 31523482
83 + 31523399 = 31523482
101 + 31523381 = 31523482
173 + 31523309 = 31523482
239 + 31523243 = 31523482
251 + 31523231 = 31523482

Showing the first eight; more decompositions exist.
