Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158530, here are decompositions:

3 + 158527 = 158530
11 + 158519 = 158530
23 + 158507 = 158530
41 + 158489 = 158530
101 + 158429 = 158530
137 + 158393 = 158530
167 + 158363 = 158530
173 + 158357 = 158530

Showing the first eight; more decompositions exist.
