Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454958, here are decompositions:

5 + 31454953 = 31454958
131 + 31454827 = 31454958
149 + 31454809 = 31454958
257 + 31454701 = 31454958
277 + 31454681 = 31454958
307 + 31454651 = 31454958
331 + 31454627 = 31454958
461 + 31454497 = 31454958

Showing the first eight; more decompositions exist.
