Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460154, here are decompositions:

17 + 31460137 = 31460154
101 + 31460053 = 31460154
137 + 31460017 = 31460154
191 + 31459963 = 31460154
223 + 31459931 = 31460154
263 + 31459891 = 31460154
307 + 31459847 = 31460154
347 + 31459807 = 31460154

Showing the first eight; more decompositions exist.
