Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118458, here are decompositions:

5 + 118453 = 118458
29 + 118429 = 118458
47 + 118411 = 118458
59 + 118399 = 118458
71 + 118387 = 118458
89 + 118369 = 118458
97 + 118361 = 118458
181 + 118277 = 118458

Showing the first eight; more decompositions exist.
