Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481180, here are decompositions:

3 + 481177 = 481180
23 + 481157 = 481180
47 + 481133 = 481180
71 + 481109 = 481180
83 + 481097 = 481180
107 + 481073 = 481180
113 + 481067 = 481180
137 + 481043 = 481180

Showing the first eight; more decompositions exist.
