Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595434, here are decompositions:

41 + 31595393 = 31595434
47 + 31595387 = 31595434
71 + 31595363 = 31595434
191 + 31595243 = 31595434
197 + 31595237 = 31595434
257 + 31595177 = 31595434
293 + 31595141 = 31595434
443 + 31594991 = 31595434

Showing the first eight; more decompositions exist.
