Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78938, here are decompositions:

19 + 78919 = 78938
37 + 78901 = 78938
61 + 78877 = 78938
151 + 78787 = 78938
157 + 78781 = 78938
241 + 78697 = 78938
331 + 78607 = 78938
367 + 78571 = 78938

Showing the first eight; more decompositions exist.
