Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628058, here are decompositions:

37 + 31628021 = 31628058
41 + 31628017 = 31628058
47 + 31628011 = 31628058
79 + 31627979 = 31628058
89 + 31627969 = 31628058
97 + 31627961 = 31628058
109 + 31627949 = 31628058
127 + 31627931 = 31628058

Showing the first eight; more decompositions exist.
