Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460954, here are decompositions:

3 + 31460951 = 31460954
37 + 31460917 = 31460954
103 + 31460851 = 31460954
163 + 31460791 = 31460954
211 + 31460743 = 31460954
277 + 31460677 = 31460954
307 + 31460647 = 31460954
373 + 31460581 = 31460954

Showing the first eight; more decompositions exist.
