Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559126, here are decompositions:

163 + 31558963 = 31559126
199 + 31558927 = 31559126
229 + 31558897 = 31559126
283 + 31558843 = 31559126
307 + 31558819 = 31559126
337 + 31558789 = 31559126
367 + 31558759 = 31559126
397 + 31558729 = 31559126

Showing the first eight; more decompositions exist.
