Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627080, here are decompositions:

7 + 31627073 = 31627080
11 + 31627069 = 31627080
29 + 31627051 = 31627080
47 + 31627033 = 31627080
53 + 31627027 = 31627080
73 + 31627007 = 31627080
101 + 31626979 = 31627080
103 + 31626977 = 31627080

Showing the first eight; more decompositions exist.
