Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595198, here are decompositions:

97 + 31595101 = 31595198
139 + 31595059 = 31595198
199 + 31594999 = 31595198
211 + 31594987 = 31595198
331 + 31594867 = 31595198
337 + 31594861 = 31595198
499 + 31594699 = 31595198
571 + 31594627 = 31595198

Showing the first eight; more decompositions exist.
