Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595630, here are decompositions:

19 + 31595611 = 31595630
37 + 31595593 = 31595630
61 + 31595569 = 31595630
163 + 31595467 = 31595630
223 + 31595407 = 31595630
379 + 31595251 = 31595630
421 + 31595209 = 31595630
457 + 31595173 = 31595630

Showing the first eight; more decompositions exist.
