Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628346, here are decompositions:

5 + 31628341 = 31628346
19 + 31628327 = 31628346
73 + 31628273 = 31628346
97 + 31628249 = 31628346
107 + 31628239 = 31628346
173 + 31628173 = 31628346
179 + 31628167 = 31628346
257 + 31628089 = 31628346

Showing the first eight; more decompositions exist.
