Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479686, here are decompositions:

47 + 479639 = 479686
173 + 479513 = 479686
197 + 479489 = 479686
257 + 479429 = 479686
359 + 479327 = 479686
419 + 479267 = 479686
443 + 479243 = 479686
659 + 479027 = 479686

Showing the first eight; more decompositions exist.
