Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499592, here are decompositions:

31 + 31499561 = 31499592
101 + 31499491 = 31499592
181 + 31499411 = 31499592
191 + 31499401 = 31499592
193 + 31499399 = 31499592
251 + 31499341 = 31499592
263 + 31499329 = 31499592
269 + 31499323 = 31499592

Showing the first eight; more decompositions exist.
