Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169874, here are decompositions:

31 + 169843 = 169874
37 + 169837 = 169874
43 + 169831 = 169874
97 + 169777 = 169874
181 + 169693 = 169874
193 + 169681 = 169874
241 + 169633 = 169874
283 + 169591 = 169874

Showing the first eight; more decompositions exist.
