Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58158, here are decompositions:

5 + 58153 = 58158
7 + 58151 = 58158
11 + 58147 = 58158
29 + 58129 = 58158
47 + 58111 = 58158
59 + 58099 = 58158
97 + 58061 = 58158
101 + 58057 = 58158

Showing the first eight; more decompositions exist.
