Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42658, here are decompositions:

17 + 42641 = 42658
47 + 42611 = 42658
89 + 42569 = 42658
101 + 42557 = 42658
149 + 42509 = 42658
167 + 42491 = 42658
191 + 42467 = 42658
197 + 42461 = 42658

Showing the first eight; more decompositions exist.
