Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43690, here are decompositions:

29 + 43661 = 43690
41 + 43649 = 43690
83 + 43607 = 43690
113 + 43577 = 43690
149 + 43541 = 43690
173 + 43517 = 43690
191 + 43499 = 43690
233 + 43457 = 43690

Showing the first eight; more decompositions exist.
