Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124158, here are decompositions:

5 + 124153 = 124158
11 + 124147 = 124158
19 + 124139 = 124158
37 + 124121 = 124158
61 + 124097 = 124158
71 + 124087 = 124158
137 + 124021 = 124158
157 + 124001 = 124158

Showing the first eight; more decompositions exist.
