Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542354, here are decompositions:

13 + 31542341 = 31542354
31 + 31542323 = 31542354
73 + 31542281 = 31542354
157 + 31542197 = 31542354
191 + 31542163 = 31542354
241 + 31542113 = 31542354
251 + 31542103 = 31542354
271 + 31542083 = 31542354

Showing the first eight; more decompositions exist.
