Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628110, here are decompositions:

11 + 31628099 = 31628110
89 + 31628021 = 31628110
131 + 31627979 = 31628110
149 + 31627961 = 31628110
179 + 31627931 = 31628110
317 + 31627793 = 31628110
347 + 31627763 = 31628110
359 + 31627751 = 31628110

Showing the first eight; more decompositions exist.
