Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595078, here are decompositions:

19 + 31595059 = 31595078
79 + 31594999 = 31595078
211 + 31594867 = 31595078
271 + 31594807 = 31595078
331 + 31594747 = 31595078
349 + 31594729 = 31595078
379 + 31594699 = 31595078
397 + 31594681 = 31595078

Showing the first eight; more decompositions exist.
