Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482248, here are decompositions:

19 + 31482229 = 31482248
79 + 31482169 = 31482248
151 + 31482097 = 31482248
181 + 31482067 = 31482248
211 + 31482037 = 31482248
337 + 31481911 = 31482248
349 + 31481899 = 31482248
397 + 31481851 = 31482248

Showing the first eight; more decompositions exist.
