Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481398, here are decompositions:

11 + 481387 = 481398
19 + 481379 = 481398
97 + 481301 = 481398
101 + 481297 = 481398
149 + 481249 = 481398
167 + 481231 = 481398
191 + 481207 = 481398
199 + 481199 = 481398

Showing the first eight; more decompositions exist.
