Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78980, here are decompositions:

3 + 78977 = 78980
61 + 78919 = 78980
79 + 78901 = 78980
103 + 78877 = 78980
127 + 78853 = 78980
157 + 78823 = 78980
193 + 78787 = 78980
199 + 78781 = 78980

Showing the first eight; more decompositions exist.
