Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487222, here are decompositions:

3 + 487219 = 487222
11 + 487211 = 487222
89 + 487133 = 487222
149 + 487073 = 487222
173 + 487049 = 487222
251 + 486971 = 487222
293 + 486929 = 487222
353 + 486869 = 487222

Showing the first eight; more decompositions exist.
