Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484244, here are decompositions:

5 + 31484239 = 31484244
7 + 31484237 = 31484244
37 + 31484207 = 31484244
41 + 31484203 = 31484244
67 + 31484177 = 31484244
83 + 31484161 = 31484244
101 + 31484143 = 31484244
151 + 31484093 = 31484244

Showing the first eight; more decompositions exist.
