Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8980, here are decompositions:

11 + 8969 = 8980
17 + 8963 = 8980
29 + 8951 = 8980
47 + 8933 = 8980
113 + 8867 = 8980
131 + 8849 = 8980
149 + 8831 = 8980
173 + 8807 = 8980

Showing the first eight; more decompositions exist.
