Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594884, here are decompositions:

7 + 31594877 = 31594884
11 + 31594873 = 31594884
17 + 31594867 = 31594884
23 + 31594861 = 31594884
71 + 31594813 = 31594884
73 + 31594811 = 31594884
127 + 31594757 = 31594884
137 + 31594747 = 31594884

Showing the first eight; more decompositions exist.
