Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482856, here are decompositions:

17 + 31482839 = 31482856
23 + 31482833 = 31482856
113 + 31482743 = 31482856
149 + 31482707 = 31482856
173 + 31482683 = 31482856
239 + 31482617 = 31482856
257 + 31482599 = 31482856
269 + 31482587 = 31482856

Showing the first eight; more decompositions exist.
