Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595554, here are decompositions:

71 + 31595483 = 31595554
167 + 31595387 = 31595554
191 + 31595363 = 31595554
281 + 31595273 = 31595554
311 + 31595243 = 31595554
317 + 31595237 = 31595554
491 + 31595063 = 31595554
563 + 31594991 = 31595554

Showing the first eight; more decompositions exist.
