Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594980, here are decompositions:

17 + 31594963 = 31594980
19 + 31594961 = 31594980
61 + 31594919 = 31594980
73 + 31594907 = 31594980
97 + 31594883 = 31594980
103 + 31594877 = 31594980
107 + 31594873 = 31594980
113 + 31594867 = 31594980

Showing the first eight; more decompositions exist.
