Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487618, here are decompositions:

11 + 487607 = 487618
17 + 487601 = 487618
29 + 487589 = 487618
137 + 487481 = 487618
149 + 487469 = 487618
191 + 487427 = 487618
227 + 487391 = 487618
269 + 487349 = 487618

Showing the first eight; more decompositions exist.
