Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78920, here are decompositions:

19 + 78901 = 78920
31 + 78889 = 78920
43 + 78877 = 78920
67 + 78853 = 78920
97 + 78823 = 78920
139 + 78781 = 78920
199 + 78721 = 78920
223 + 78697 = 78920

Showing the first eight; more decompositions exist.
