Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532474, here are decompositions:

37 + 31532437 = 31532474
73 + 31532401 = 31532474
151 + 31532323 = 31532474
271 + 31532203 = 31532474
307 + 31532167 = 31532474
661 + 31531813 = 31532474
991 + 31531483 = 31532474
1021 + 31531453 = 31532474

Showing the first eight; more decompositions exist.
