Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626048, here are decompositions:

7 + 31626041 = 31626048
29 + 31626019 = 31626048
37 + 31626011 = 31626048
61 + 31625987 = 31626048
67 + 31625981 = 31626048
79 + 31625969 = 31626048
109 + 31625939 = 31626048
131 + 31625917 = 31626048

Showing the first eight; more decompositions exist.
