Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169984, here are decompositions:

41 + 169943 = 169984
47 + 169937 = 169984
71 + 169913 = 169984
167 + 169817 = 169984
233 + 169751 = 169984
251 + 169733 = 169984
293 + 169691 = 169984
317 + 169667 = 169984

Showing the first eight; more decompositions exist.
