Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78786, here are decompositions:

5 + 78781 = 78786
7 + 78779 = 78786
73 + 78713 = 78786
79 + 78707 = 78786
89 + 78697 = 78786
137 + 78649 = 78786
163 + 78623 = 78786
179 + 78607 = 78786

Showing the first eight; more decompositions exist.
