Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595246, here are decompositions:

3 + 31595243 = 31595246
37 + 31595209 = 31595246
73 + 31595173 = 31595246
283 + 31594963 = 31595246
373 + 31594873 = 31595246
379 + 31594867 = 31595246
433 + 31594813 = 31595246
439 + 31594807 = 31595246

Showing the first eight; more decompositions exist.
