Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169854, here are decompositions:

11 + 169843 = 169854
17 + 169837 = 169854
23 + 169831 = 169854
31 + 169823 = 169854
37 + 169817 = 169854
71 + 169783 = 169854
101 + 169753 = 169854
103 + 169751 = 169854

Showing the first eight; more decompositions exist.
