Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628062, here are decompositions:

41 + 31628021 = 31628062
83 + 31627979 = 31628062
101 + 31627961 = 31628062
113 + 31627949 = 31628062
131 + 31627931 = 31628062
173 + 31627889 = 31628062
251 + 31627811 = 31628062
269 + 31627793 = 31628062

Showing the first eight; more decompositions exist.
