Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20850, here are decompositions:

41 + 20809 = 20850
43 + 20807 = 20850
61 + 20789 = 20850
79 + 20771 = 20850
97 + 20753 = 20850
101 + 20749 = 20850
103 + 20747 = 20850
107 + 20743 = 20850

Showing the first eight; more decompositions exist.
