Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532412, here are decompositions:

11 + 31532401 = 31532412
59 + 31532353 = 31532412
71 + 31532341 = 31532412
73 + 31532339 = 31532412
83 + 31532329 = 31532412
89 + 31532323 = 31532412
151 + 31532261 = 31532412
193 + 31532219 = 31532412

Showing the first eight; more decompositions exist.
