Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478378, here are decompositions:

107 + 478271 = 478378
137 + 478241 = 478378
179 + 478199 = 478378
239 + 478139 = 478378
311 + 478067 = 478378
401 + 477977 = 478378
431 + 477947 = 478378
479 + 477899 = 478378

Showing the first eight; more decompositions exist.
