Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15458, here are decompositions:

7 + 15451 = 15458
19 + 15439 = 15458
31 + 15427 = 15458
67 + 15391 = 15458
97 + 15361 = 15458
109 + 15349 = 15458
127 + 15331 = 15458
139 + 15319 = 15458

Showing the first eight; more decompositions exist.
