Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169842, here are decompositions:

5 + 169837 = 169842
11 + 169831 = 169842
19 + 169823 = 169842
53 + 169789 = 169842
59 + 169783 = 169842
73 + 169769 = 169842
89 + 169753 = 169842
109 + 169733 = 169842

Showing the first eight; more decompositions exist.
