Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481438, here are decompositions:

5 + 481433 = 481438
29 + 481409 = 481438
59 + 481379 = 481438
131 + 481307 = 481438
137 + 481301 = 481438
227 + 481211 = 481438
239 + 481199 = 481438
257 + 481181 = 481438

Showing the first eight; more decompositions exist.
