Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473560, here are decompositions:

31 + 31473529 = 31473560
37 + 31473523 = 31473560
73 + 31473487 = 31473560
103 + 31473457 = 31473560
163 + 31473397 = 31473560
229 + 31473331 = 31473560
277 + 31473283 = 31473560
373 + 31473187 = 31473560

Showing the first eight; more decompositions exist.
