Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532442, here are decompositions:

5 + 31532437 = 31532442
13 + 31532429 = 31532442
41 + 31532401 = 31532442
89 + 31532353 = 31532442
101 + 31532341 = 31532442
103 + 31532339 = 31532442
113 + 31532329 = 31532442
163 + 31532279 = 31532442

Showing the first eight; more decompositions exist.
