Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104378, here are decompositions:

31 + 104347 = 104378
67 + 104311 = 104378
97 + 104281 = 104378
139 + 104239 = 104378
199 + 104179 = 104378
229 + 104149 = 104378
271 + 104107 = 104378
331 + 104047 = 104378

Showing the first eight; more decompositions exist.
