Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484384, here are decompositions:

7 + 31484377 = 31484384
31 + 31484353 = 31484384
67 + 31484317 = 31484384
103 + 31484281 = 31484384
181 + 31484203 = 31484384
223 + 31484161 = 31484384
241 + 31484143 = 31484384
313 + 31484071 = 31484384

Showing the first eight; more decompositions exist.
