Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78722, here are decompositions:

31 + 78691 = 78722
73 + 78649 = 78722
79 + 78643 = 78722
139 + 78583 = 78722
151 + 78571 = 78722
181 + 78541 = 78722
211 + 78511 = 78722
283 + 78439 = 78722

Showing the first eight; more decompositions exist.
