Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595446, here are decompositions:

53 + 31595393 = 31595446
59 + 31595387 = 31595446
83 + 31595363 = 31595446
167 + 31595279 = 31595446
173 + 31595273 = 31595446
227 + 31595219 = 31595446
257 + 31595189 = 31595446
269 + 31595177 = 31595446

Showing the first eight; more decompositions exist.
