Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627086, here are decompositions:

13 + 31627073 = 31627086
17 + 31627069 = 31627086
53 + 31627033 = 31627086
59 + 31627027 = 31627086
79 + 31627007 = 31627086
107 + 31626979 = 31627086
109 + 31626977 = 31627086
193 + 31626893 = 31627086

Showing the first eight; more decompositions exist.
