Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595344, here are decompositions:

71 + 31595273 = 31595344
101 + 31595243 = 31595344
107 + 31595237 = 31595344
167 + 31595177 = 31595344
281 + 31595063 = 31595344
353 + 31594991 = 31595344
383 + 31594961 = 31595344
461 + 31594883 = 31595344

Showing the first eight; more decompositions exist.
