Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595684, here are decompositions:

13 + 31595671 = 31595684
31 + 31595653 = 31595684
73 + 31595611 = 31595684
103 + 31595581 = 31595684
277 + 31595407 = 31595684
313 + 31595371 = 31595684
433 + 31595251 = 31595684
811 + 31594873 = 31595684

Showing the first eight; more decompositions exist.
