Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499476, here are decompositions:

17 + 31499459 = 31499476
89 + 31499387 = 31499476
149 + 31499327 = 31499476
167 + 31499309 = 31499476
179 + 31499297 = 31499476
293 + 31499183 = 31499476
317 + 31499159 = 31499476
419 + 31499057 = 31499476

Showing the first eight; more decompositions exist.
