Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484230, here are decompositions:

23 + 31484207 = 31484230
53 + 31484177 = 31484230
101 + 31484129 = 31484230
137 + 31484093 = 31484230
149 + 31484081 = 31484230
251 + 31483979 = 31484230
311 + 31483919 = 31484230
317 + 31483913 = 31484230

Showing the first eight; more decompositions exist.
