Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158388, here are decompositions:

17 + 158371 = 158388
29 + 158359 = 158388
31 + 158357 = 158388
37 + 158351 = 158388
47 + 158341 = 158388
59 + 158329 = 158388
127 + 158261 = 158388
157 + 158231 = 158388

Showing the first eight; more decompositions exist.
