Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481388, here are decompositions:

139 + 481249 = 481388
157 + 481231 = 481388
181 + 481207 = 481388
211 + 481177 = 481388
241 + 481147 = 481388
337 + 481051 = 481388
367 + 481021 = 481388
379 + 481009 = 481388

Showing the first eight; more decompositions exist.
