Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595192, here are decompositions:

3 + 31595189 = 31595192
19 + 31595173 = 31595192
193 + 31594999 = 31595192
229 + 31594963 = 31595192
331 + 31594861 = 31595192
379 + 31594813 = 31595192
463 + 31594729 = 31595192
613 + 31594579 = 31595192

Showing the first eight; more decompositions exist.
