Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78708, here are decompositions:

11 + 78697 = 78708
17 + 78691 = 78708
59 + 78649 = 78708
101 + 78607 = 78708
131 + 78577 = 78708
137 + 78571 = 78708
139 + 78569 = 78708
167 + 78541 = 78708

Showing the first eight; more decompositions exist.
