Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595452, here are decompositions:

59 + 31595393 = 31595452
89 + 31595363 = 31595452
173 + 31595279 = 31595452
179 + 31595273 = 31595452
233 + 31595219 = 31595452
263 + 31595189 = 31595452
311 + 31595141 = 31595452
389 + 31595063 = 31595452

Showing the first eight; more decompositions exist.
