Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595494, here are decompositions:

11 + 31595483 = 31595494
101 + 31595393 = 31595494
107 + 31595387 = 31595494
131 + 31595363 = 31595494
251 + 31595243 = 31595494
257 + 31595237 = 31595494
317 + 31595177 = 31595494
353 + 31595141 = 31595494

Showing the first eight; more decompositions exist.
