Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484584, here are decompositions:

41 + 31484543 = 31484584
71 + 31484513 = 31484584
167 + 31484417 = 31484584
281 + 31484303 = 31484584
317 + 31484267 = 31484584
347 + 31484237 = 31484584
491 + 31484093 = 31484584
503 + 31484081 = 31484584

Showing the first eight; more decompositions exist.
