Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103978, here are decompositions:

11 + 103967 = 103978
59 + 103919 = 103978
89 + 103889 = 103978
137 + 103841 = 103978
167 + 103811 = 103978
191 + 103787 = 103978
359 + 103619 = 103978
401 + 103577 = 103978

Showing the first eight; more decompositions exist.
