Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7850, here are decompositions:

61 + 7789 = 7850
97 + 7753 = 7850
109 + 7741 = 7850
127 + 7723 = 7850
151 + 7699 = 7850
163 + 7687 = 7850
181 + 7669 = 7850
211 + 7639 = 7850

Showing the first eight; more decompositions exist.
