Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523460, here are decompositions:

19 + 31523441 = 31523460
41 + 31523419 = 31523460
53 + 31523407 = 31523460
61 + 31523399 = 31523460
79 + 31523381 = 31523460
113 + 31523347 = 31523460
131 + 31523329 = 31523460
151 + 31523309 = 31523460

Showing the first eight; more decompositions exist.
