Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78890, here are decompositions:

3 + 78887 = 78890
13 + 78877 = 78890
37 + 78853 = 78890
67 + 78823 = 78890
103 + 78787 = 78890
109 + 78781 = 78890
193 + 78697 = 78890
199 + 78691 = 78890

Showing the first eight; more decompositions exist.
