Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499182, here are decompositions:

23 + 31499159 = 31499182
149 + 31499033 = 31499182
179 + 31499003 = 31499182
191 + 31498991 = 31499182
233 + 31498949 = 31499182
251 + 31498931 = 31499182
269 + 31498913 = 31499182
353 + 31498829 = 31499182

Showing the first eight; more decompositions exist.
