Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559294, here are decompositions:

31 + 31559263 = 31559294
43 + 31559251 = 31559294
163 + 31559131 = 31559294
223 + 31559071 = 31559294
331 + 31558963 = 31559294
337 + 31558957 = 31559294
367 + 31558927 = 31559294
397 + 31558897 = 31559294

Showing the first eight; more decompositions exist.
