Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460244, here are decompositions:

47 + 31460197 = 31460244
71 + 31460173 = 31460244
107 + 31460137 = 31460244
181 + 31460063 = 31460244
191 + 31460053 = 31460244
227 + 31460017 = 31460244
251 + 31459993 = 31460244
281 + 31459963 = 31460244

Showing the first eight; more decompositions exist.
