Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101458, here are decompositions:

29 + 101429 = 101458
47 + 101411 = 101458
59 + 101399 = 101458
179 + 101279 = 101458
191 + 101267 = 101458
251 + 101207 = 101458
317 + 101141 = 101458
347 + 101111 = 101458

Showing the first eight; more decompositions exist.
