Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499536, here are decompositions:

137 + 31499399 = 31499536
149 + 31499387 = 31499536
227 + 31499309 = 31499536
239 + 31499297 = 31499536
269 + 31499267 = 31499536
347 + 31499189 = 31499536
353 + 31499183 = 31499536
479 + 31499057 = 31499536

Showing the first eight; more decompositions exist.
