Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595252, here are decompositions:

43 + 31595209 = 31595252
79 + 31595173 = 31595252
151 + 31595101 = 31595252
193 + 31595059 = 31595252
349 + 31594903 = 31595252
379 + 31594873 = 31595252
439 + 31594813 = 31595252
523 + 31594729 = 31595252

Showing the first eight; more decompositions exist.
