Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481146, here are decompositions:

5 + 481141 = 481146
13 + 481133 = 481146
23 + 481123 = 481146
37 + 481109 = 481146
53 + 481093 = 481146
59 + 481087 = 481146
73 + 481073 = 481146
79 + 481067 = 481146

Showing the first eight; more decompositions exist.
