Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499346, here are decompositions:

5 + 31499341 = 31499346
17 + 31499329 = 31499346
19 + 31499327 = 31499346
23 + 31499323 = 31499346
37 + 31499309 = 31499346
79 + 31499267 = 31499346
107 + 31499239 = 31499346
157 + 31499189 = 31499346

Showing the first eight; more decompositions exist.
