Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7898, here are decompositions:

19 + 7879 = 7898
31 + 7867 = 7898
109 + 7789 = 7898
139 + 7759 = 7898
157 + 7741 = 7898
181 + 7717 = 7898
199 + 7699 = 7898
211 + 7687 = 7898

Showing the first eight; more decompositions exist.
