Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481542, here are decompositions:

11 + 481531 = 481542
29 + 481513 = 481542
41 + 481501 = 481542
53 + 481489 = 481542
73 + 481469 = 481542
109 + 481433 = 481542
163 + 481379 = 481542
179 + 481363 = 481542

Showing the first eight; more decompositions exist.
