Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484566, here are decompositions:

23 + 31484543 = 31484566
53 + 31484513 = 31484566
149 + 31484417 = 31484566
227 + 31484339 = 31484566
263 + 31484303 = 31484566
359 + 31484207 = 31484566
389 + 31484177 = 31484566
587 + 31483979 = 31484566

Showing the first eight; more decompositions exist.
