Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499482, here are decompositions:

23 + 31499459 = 31499482
71 + 31499411 = 31499482
83 + 31499399 = 31499482
173 + 31499309 = 31499482
191 + 31499291 = 31499482
251 + 31499231 = 31499482
293 + 31499189 = 31499482
419 + 31499063 = 31499482

Showing the first eight; more decompositions exist.
