Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559276, here are decompositions:

13 + 31559263 = 31559276
37 + 31559239 = 31559276
127 + 31559149 = 31559276
283 + 31558993 = 31559276
313 + 31558963 = 31559276
337 + 31558939 = 31559276
349 + 31558927 = 31559276
379 + 31558897 = 31559276

Showing the first eight; more decompositions exist.
