Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78740, here are decompositions:

3 + 78737 = 78740
19 + 78721 = 78740
43 + 78697 = 78740
97 + 78643 = 78740
157 + 78583 = 78740
163 + 78577 = 78740
199 + 78541 = 78740
223 + 78517 = 78740

Showing the first eight; more decompositions exist.
