Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481288, here are decompositions:

89 + 481199 = 481288
107 + 481181 = 481288
131 + 481157 = 481288
179 + 481109 = 481288
191 + 481097 = 481288
347 + 480941 = 481288
359 + 480929 = 481288
449 + 480839 = 481288

Showing the first eight; more decompositions exist.
