Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171910, here are decompositions:

29 + 171881 = 171910
41 + 171869 = 171910
47 + 171863 = 171910
59 + 171851 = 171910
83 + 171827 = 171910
107 + 171803 = 171910
149 + 171761 = 171910
191 + 171719 = 171910

Showing the first eight; more decompositions exist.
