Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83684, here are decompositions:

31 + 83653 = 83684
43 + 83641 = 83684
67 + 83617 = 83684
127 + 83557 = 83684
241 + 83443 = 83684
277 + 83407 = 83684
283 + 83401 = 83684
373 + 83311 = 83684

Showing the first eight; more decompositions exist.
