Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10180, here are decompositions:

3 + 10177 = 10180
11 + 10169 = 10180
17 + 10163 = 10180
29 + 10151 = 10180
41 + 10139 = 10180
47 + 10133 = 10180
89 + 10091 = 10180
101 + 10079 = 10180

Showing the first eight; more decompositions exist.
