Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78690, here are decompositions:

37 + 78653 = 78690
41 + 78649 = 78690
47 + 78643 = 78690
67 + 78623 = 78690
83 + 78607 = 78690
97 + 78593 = 78690
107 + 78583 = 78690
113 + 78577 = 78690

Showing the first eight; more decompositions exist.
