Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452954, here are decompositions:

11 + 31452943 = 31452954
53 + 31452901 = 31452954
103 + 31452851 = 31452954
151 + 31452803 = 31452954
191 + 31452763 = 31452954
223 + 31452731 = 31452954
227 + 31452727 = 31452954
233 + 31452721 = 31452954

Showing the first eight; more decompositions exist.
