Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532340, here are decompositions:

11 + 31532329 = 31532340
17 + 31532323 = 31532340
61 + 31532279 = 31532340
71 + 31532269 = 31532340
79 + 31532261 = 31532340
113 + 31532227 = 31532340
131 + 31532209 = 31532340
137 + 31532203 = 31532340

Showing the first eight; more decompositions exist.
