Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78686, here are decompositions:

37 + 78649 = 78686
43 + 78643 = 78686
79 + 78607 = 78686
103 + 78583 = 78686
109 + 78577 = 78686
199 + 78487 = 78686
379 + 78307 = 78686
409 + 78277 = 78686

Showing the first eight; more decompositions exist.
