Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595424, here are decompositions:

17 + 31595407 = 31595424
31 + 31595393 = 31595424
37 + 31595387 = 31595424
41 + 31595383 = 31595424
53 + 31595371 = 31595424
61 + 31595363 = 31595424
151 + 31595273 = 31595424
173 + 31595251 = 31595424

Showing the first eight; more decompositions exist.
