Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595216, here are decompositions:

7 + 31595209 = 31595216
43 + 31595173 = 31595216
157 + 31595059 = 31595216
229 + 31594987 = 31595216
313 + 31594903 = 31595216
349 + 31594867 = 31595216
409 + 31594807 = 31595216
487 + 31594729 = 31595216

Showing the first eight; more decompositions exist.
