Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487444, here are decompositions:

17 + 487427 = 487444
47 + 487397 = 487444
53 + 487391 = 487444
131 + 487313 = 487444
137 + 487307 = 487444
197 + 487247 = 487444
233 + 487211 = 487444
257 + 487187 = 487444

Showing the first eight; more decompositions exist.
