Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532358, here are decompositions:

5 + 31532353 = 31532358
17 + 31532341 = 31532358
19 + 31532339 = 31532358
29 + 31532329 = 31532358
79 + 31532279 = 31532358
89 + 31532269 = 31532358
97 + 31532261 = 31532358
131 + 31532227 = 31532358

Showing the first eight; more decompositions exist.
