Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547454, here are decompositions:

5 + 31547449 = 31547454
13 + 31547441 = 31547454
41 + 31547413 = 31547454
97 + 31547357 = 31547454
137 + 31547317 = 31547454
151 + 31547303 = 31547454
157 + 31547297 = 31547454
167 + 31547287 = 31547454

Showing the first eight; more decompositions exist.
