Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595546, here are decompositions:

79 + 31595467 = 31595546
139 + 31595407 = 31595546
163 + 31595383 = 31595546
337 + 31595209 = 31595546
373 + 31595173 = 31595546
487 + 31595059 = 31595546
547 + 31594999 = 31595546
643 + 31594903 = 31595546

Showing the first eight; more decompositions exist.
