Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532454, here are decompositions:

17 + 31532437 = 31532454
53 + 31532401 = 31532454
101 + 31532353 = 31532454
113 + 31532341 = 31532454
131 + 31532323 = 31532454
193 + 31532261 = 31532454
227 + 31532227 = 31532454
251 + 31532203 = 31532454

Showing the first eight; more decompositions exist.
