Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481200, here are decompositions:

19 + 481181 = 481200
23 + 481177 = 481200
29 + 481171 = 481200
43 + 481157 = 481200
47 + 481153 = 481200
53 + 481147 = 481200
59 + 481141 = 481200
67 + 481133 = 481200

Showing the first eight; more decompositions exist.
