Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460028, here are decompositions:

11 + 31460017 = 31460028
29 + 31459999 = 31460028
79 + 31459949 = 31460028
97 + 31459931 = 31460028
137 + 31459891 = 31460028
179 + 31459849 = 31460028
181 + 31459847 = 31460028
199 + 31459829 = 31460028

Showing the first eight; more decompositions exist.
