Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595394, here are decompositions:

7 + 31595387 = 31595394
11 + 31595383 = 31595394
23 + 31595371 = 31595394
31 + 31595363 = 31595394
151 + 31595243 = 31595394
157 + 31595237 = 31595394
293 + 31595101 = 31595394
331 + 31595063 = 31595394

Showing the first eight; more decompositions exist.
