Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595482, here are decompositions:

89 + 31595393 = 31595482
239 + 31595243 = 31595482
263 + 31595219 = 31595482
293 + 31595189 = 31595482
419 + 31595063 = 31595482
461 + 31595021 = 31595482
491 + 31594991 = 31595482
521 + 31594961 = 31595482

Showing the first eight; more decompositions exist.
