Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481488, here are decompositions:

19 + 481469 = 481488
41 + 481447 = 481488
71 + 481417 = 481488
79 + 481409 = 481488
101 + 481387 = 481488
109 + 481379 = 481488
181 + 481307 = 481488
191 + 481297 = 481488

Showing the first eight; more decompositions exist.
