Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487228, here are decompositions:

17 + 487211 = 487228
41 + 487187 = 487228
149 + 487079 = 487228
179 + 487049 = 487228
251 + 486977 = 487228
257 + 486971 = 487228
281 + 486947 = 487228
359 + 486869 = 487228

Showing the first eight; more decompositions exist.
