Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173890, here are decompositions:

23 + 173867 = 173890
29 + 173861 = 173890
71 + 173819 = 173890
83 + 173807 = 173890
107 + 173783 = 173890
113 + 173777 = 173890
149 + 173741 = 173890
191 + 173699 = 173890

Showing the first eight; more decompositions exist.
