Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493454, here are decompositions:

7 + 31493447 = 31493454
11 + 31493443 = 31493454
101 + 31493353 = 31493454
107 + 31493347 = 31493454
131 + 31493323 = 31493454
163 + 31493291 = 31493454
263 + 31493191 = 31493454
283 + 31493171 = 31493454

Showing the first eight; more decompositions exist.
