Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628332, here are decompositions:

5 + 31628327 = 31628332
41 + 31628291 = 31628332
59 + 31628273 = 31628332
83 + 31628249 = 31628332
233 + 31628099 = 31628332
311 + 31628021 = 31628332
353 + 31627979 = 31628332
383 + 31627949 = 31628332

Showing the first eight; more decompositions exist.
