Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78636, here are decompositions:

13 + 78623 = 78636
29 + 78607 = 78636
43 + 78593 = 78636
53 + 78583 = 78636
59 + 78577 = 78636
67 + 78569 = 78636
83 + 78553 = 78636
97 + 78539 = 78636

Showing the first eight; more decompositions exist.
