Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166130, here are decompositions:

31 + 166099 = 166130
67 + 166063 = 166130
103 + 166027 = 166130
109 + 166021 = 166130
199 + 165931 = 166130
229 + 165901 = 166130
313 + 165817 = 166130
331 + 165799 = 166130

Showing the first eight; more decompositions exist.
