Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595410, here are decompositions:

3 + 31595407 = 31595410
17 + 31595393 = 31595410
23 + 31595387 = 31595410
47 + 31595363 = 31595410
131 + 31595279 = 31595410
137 + 31595273 = 31595410
167 + 31595243 = 31595410
173 + 31595237 = 31595410

Showing the first eight; more decompositions exist.
