Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13058, here are decompositions:

79 + 12979 = 13058
139 + 12919 = 13058
151 + 12907 = 13058
229 + 12829 = 13058
277 + 12781 = 13058
337 + 12721 = 13058
421 + 12637 = 13058
439 + 12619 = 13058

Showing the first eight; more decompositions exist.
