Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481284, here are decompositions:

53 + 481231 = 481284
73 + 481211 = 481284
103 + 481181 = 481284
107 + 481177 = 481284
113 + 481171 = 481284
127 + 481157 = 481284
131 + 481153 = 481284
137 + 481147 = 481284

Showing the first eight; more decompositions exist.
