Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595454, here are decompositions:

47 + 31595407 = 31595454
61 + 31595393 = 31595454
67 + 31595387 = 31595454
71 + 31595383 = 31595454
83 + 31595371 = 31595454
181 + 31595273 = 31595454
211 + 31595243 = 31595454
277 + 31595177 = 31595454

Showing the first eight; more decompositions exist.
