Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460292, here are decompositions:

11 + 31460281 = 31460292
13 + 31460279 = 31460292
29 + 31460263 = 31460292
163 + 31460129 = 31460292
229 + 31460063 = 31460292
239 + 31460053 = 31460292
293 + 31459999 = 31460292
401 + 31459891 = 31460292

Showing the first eight; more decompositions exist.
