Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173886, here are decompositions:

19 + 173867 = 173886
47 + 173839 = 173886
59 + 173827 = 173886
67 + 173819 = 173886
79 + 173807 = 173886
103 + 173783 = 173886
107 + 173779 = 173886
109 + 173777 = 173886

Showing the first eight; more decompositions exist.
