Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484458, here are decompositions:

41 + 31484417 = 31484458
191 + 31484267 = 31484458
251 + 31484207 = 31484458
281 + 31484177 = 31484458
389 + 31484069 = 31484458
479 + 31483979 = 31484458
569 + 31483889 = 31484458
587 + 31483871 = 31484458

Showing the first eight; more decompositions exist.
