Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487224, here are decompositions:

5 + 487219 = 487224
11 + 487213 = 487224
13 + 487211 = 487224
37 + 487187 = 487224
41 + 487183 = 487224
47 + 487177 = 487224
113 + 487111 = 487224
131 + 487093 = 487224

Showing the first eight; more decompositions exist.
