Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532460, here are decompositions:

23 + 31532437 = 31532460
31 + 31532429 = 31532460
59 + 31532401 = 31532460
107 + 31532353 = 31532460
131 + 31532329 = 31532460
137 + 31532323 = 31532460
181 + 31532279 = 31532460
191 + 31532269 = 31532460

Showing the first eight; more decompositions exist.
