Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626070, here are decompositions:

17 + 31626053 = 31626070
29 + 31626041 = 31626070
59 + 31626011 = 31626070
83 + 31625987 = 31626070
89 + 31625981 = 31626070
101 + 31625969 = 31626070
107 + 31625963 = 31626070
131 + 31625939 = 31626070

Showing the first eight; more decompositions exist.
