Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102958, here are decompositions:

5 + 102953 = 102958
29 + 102929 = 102958
47 + 102911 = 102958
197 + 102761 = 102958
257 + 102701 = 102958
281 + 102677 = 102958
311 + 102647 = 102958
347 + 102611 = 102958

Showing the first eight; more decompositions exist.
