Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12958, here are decompositions:

5 + 12953 = 12958
17 + 12941 = 12958
41 + 12917 = 12958
47 + 12911 = 12958
59 + 12899 = 12958
137 + 12821 = 12958
149 + 12809 = 12958
167 + 12791 = 12958

Showing the first eight; more decompositions exist.
