Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499464, here are decompositions:

5 + 31499459 = 31499464
53 + 31499411 = 31499464
137 + 31499327 = 31499464
167 + 31499297 = 31499464
173 + 31499291 = 31499464
197 + 31499267 = 31499464
233 + 31499231 = 31499464
281 + 31499183 = 31499464

Showing the first eight; more decompositions exist.
