Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12850, here are decompositions:

29 + 12821 = 12850
41 + 12809 = 12850
59 + 12791 = 12850
107 + 12743 = 12850
137 + 12713 = 12850
179 + 12671 = 12850
191 + 12659 = 12850
197 + 12653 = 12850

Showing the first eight; more decompositions exist.
