Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481206, here are decompositions:

7 + 481199 = 481206
29 + 481177 = 481206
53 + 481153 = 481206
59 + 481147 = 481206
73 + 481133 = 481206
83 + 481123 = 481206
97 + 481109 = 481206
109 + 481097 = 481206

Showing the first eight; more decompositions exist.
