Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594812, here are decompositions:

5 + 31594807 = 31594812
13 + 31594799 = 31594812
43 + 31594769 = 31594812
83 + 31594729 = 31594812
113 + 31594699 = 31594812
131 + 31594681 = 31594812
199 + 31594613 = 31594812
229 + 31594583 = 31594812

Showing the first eight; more decompositions exist.
