Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78842, here are decompositions:

3 + 78839 = 78842
19 + 78823 = 78842
61 + 78781 = 78842
151 + 78691 = 78842
193 + 78649 = 78842
199 + 78643 = 78842
271 + 78571 = 78842
331 + 78511 = 78842

Showing the first eight; more decompositions exist.
