Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481188, here are decompositions:

7 + 481181 = 481188
11 + 481177 = 481188
17 + 481171 = 481188
31 + 481157 = 481188
41 + 481147 = 481188
47 + 481141 = 481188
79 + 481109 = 481188
101 + 481087 = 481188

Showing the first eight; more decompositions exist.
