Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460256, here are decompositions:

59 + 31460197 = 31460256
83 + 31460173 = 31460256
89 + 31460167 = 31460256
127 + 31460129 = 31460256
193 + 31460063 = 31460256
239 + 31460017 = 31460256
257 + 31459999 = 31460256
263 + 31459993 = 31460256

Showing the first eight; more decompositions exist.
