Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481318, here are decompositions:

11 + 481307 = 481318
17 + 481301 = 481318
107 + 481211 = 481318
137 + 481181 = 481318
251 + 481067 = 481318
317 + 481001 = 481318
359 + 480959 = 481318
389 + 480929 = 481318

Showing the first eight; more decompositions exist.
