Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481378, here are decompositions:

5 + 481373 = 481378
71 + 481307 = 481378
167 + 481211 = 481378
179 + 481199 = 481378
197 + 481181 = 481378
269 + 481109 = 481378
281 + 481097 = 481378
311 + 481067 = 481378

Showing the first eight; more decompositions exist.
