Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499416, here are decompositions:

5 + 31499411 = 31499416
17 + 31499399 = 31499416
29 + 31499387 = 31499416
89 + 31499327 = 31499416
107 + 31499309 = 31499416
149 + 31499267 = 31499416
227 + 31499189 = 31499416
233 + 31499183 = 31499416

Showing the first eight; more decompositions exist.
