Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12862, here are decompositions:

41 + 12821 = 12862
53 + 12809 = 12862
71 + 12791 = 12862
149 + 12713 = 12862
173 + 12689 = 12862
191 + 12671 = 12862
251 + 12611 = 12862
293 + 12569 = 12862

Showing the first eight; more decompositions exist.
