Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595204, here are decompositions:

31 + 31595173 = 31595204
103 + 31595101 = 31595204
241 + 31594963 = 31595204
331 + 31594873 = 31595204
337 + 31594867 = 31595204
397 + 31594807 = 31595204
457 + 31594747 = 31595204
523 + 31594681 = 31595204

Showing the first eight; more decompositions exist.
