Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460160, here are decompositions:

23 + 31460137 = 31460160
31 + 31460129 = 31460160
97 + 31460063 = 31460160
107 + 31460053 = 31460160
167 + 31459993 = 31460160
197 + 31459963 = 31460160
211 + 31459949 = 31460160
223 + 31459937 = 31460160

Showing the first eight; more decompositions exist.
