Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166902, here are decompositions:

31 + 166871 = 166902
41 + 166861 = 166902
53 + 166849 = 166902
59 + 166843 = 166902
61 + 166841 = 166902
79 + 166823 = 166902
103 + 166799 = 166902
163 + 166739 = 166902

Showing the first eight; more decompositions exist.
