Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489686, here are decompositions:

7 + 489679 = 489686
13 + 489673 = 489686
73 + 489613 = 489686
157 + 489529 = 489686
193 + 489493 = 489686
199 + 489487 = 489686
229 + 489457 = 489686
277 + 489409 = 489686

Showing the first eight; more decompositions exist.
