Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78702, here are decompositions:

5 + 78697 = 78702
11 + 78691 = 78702
53 + 78649 = 78702
59 + 78643 = 78702
79 + 78623 = 78702
109 + 78593 = 78702
131 + 78571 = 78702
149 + 78553 = 78702

Showing the first eight; more decompositions exist.
