Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460454, here are decompositions:

13 + 31460441 = 31460454
23 + 31460431 = 31460454
41 + 31460413 = 31460454
107 + 31460347 = 31460454
163 + 31460291 = 31460454
173 + 31460281 = 31460454
191 + 31460263 = 31460454
257 + 31460197 = 31460454

Showing the first eight; more decompositions exist.
