Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524954, here are decompositions:

17 + 31524937 = 31524954
61 + 31524893 = 31524954
157 + 31524797 = 31524954
163 + 31524791 = 31524954
191 + 31524763 = 31524954
233 + 31524721 = 31524954
277 + 31524677 = 31524954
281 + 31524673 = 31524954

Showing the first eight; more decompositions exist.
