Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482844, here are decompositions:

5 + 31482839 = 31482844
11 + 31482833 = 31482844
23 + 31482821 = 31482844
83 + 31482761 = 31482844
101 + 31482743 = 31482844
137 + 31482707 = 31482844
227 + 31482617 = 31482844
257 + 31482587 = 31482844

Showing the first eight; more decompositions exist.
