Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79808, here are decompositions:

7 + 79801 = 79808
31 + 79777 = 79808
109 + 79699 = 79808
139 + 79669 = 79808
151 + 79657 = 79808
181 + 79627 = 79808
199 + 79609 = 79808
229 + 79579 = 79808

Showing the first eight; more decompositions exist.
