Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558676, here are decompositions:

3 + 31558673 = 31558676
13 + 31558663 = 31558676
43 + 31558633 = 31558676
109 + 31558567 = 31558676
157 + 31558519 = 31558676
223 + 31558453 = 31558676
277 + 31558399 = 31558676
349 + 31558327 = 31558676

Showing the first eight; more decompositions exist.
