Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171802, here are decompositions:

3 + 171799 = 171802
41 + 171761 = 171802
83 + 171719 = 171802
89 + 171713 = 171802
131 + 171671 = 171802
149 + 171653 = 171802
173 + 171629 = 171802
263 + 171539 = 171802

Showing the first eight; more decompositions exist.
