Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494470, here are decompositions:

29 + 494441 = 494470
83 + 494387 = 494470
89 + 494381 = 494470
101 + 494369 = 494470
233 + 494237 = 494470
257 + 494213 = 494470
401 + 494069 = 494470
419 + 494051 = 494470

Showing the first eight; more decompositions exist.
