Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628122, here are decompositions:

23 + 31628099 = 31628122
101 + 31628021 = 31628122
173 + 31627949 = 31628122
191 + 31627931 = 31628122
233 + 31627889 = 31628122
311 + 31627811 = 31628122
359 + 31627763 = 31628122
401 + 31627721 = 31628122

Showing the first eight; more decompositions exist.
