Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484568, here are decompositions:

107 + 31484461 = 31484568
151 + 31484417 = 31484568
191 + 31484377 = 31484568
229 + 31484339 = 31484568
251 + 31484317 = 31484568
331 + 31484237 = 31484568
359 + 31484209 = 31484568
389 + 31484179 = 31484568

Showing the first eight; more decompositions exist.
