Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487308, here are decompositions:

5 + 487303 = 487308
47 + 487261 = 487308
61 + 487247 = 487308
89 + 487219 = 487308
97 + 487211 = 487308
131 + 487177 = 487308
197 + 487111 = 487308
229 + 487079 = 487308

Showing the first eight; more decompositions exist.
