Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460250, here are decompositions:

53 + 31460197 = 31460250
83 + 31460167 = 31460250
113 + 31460137 = 31460250
197 + 31460053 = 31460250
233 + 31460017 = 31460250
251 + 31459999 = 31460250
257 + 31459993 = 31460250
313 + 31459937 = 31460250

Showing the first eight; more decompositions exist.
