Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499214, here are decompositions:

31 + 31499183 = 31499214
53 + 31499161 = 31499214
107 + 31499107 = 31499214
137 + 31499077 = 31499214
151 + 31499063 = 31499214
157 + 31499057 = 31499214
181 + 31499033 = 31499214
191 + 31499023 = 31499214

Showing the first eight; more decompositions exist.
