Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130858, here are decompositions:

17 + 130841 = 130858
29 + 130829 = 130858
41 + 130817 = 130858
47 + 130811 = 130858
71 + 130787 = 130858
89 + 130769 = 130858
227 + 130631 = 130858
239 + 130619 = 130858

Showing the first eight; more decompositions exist.
