Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494520, here are decompositions:

23 + 494497 = 494520
79 + 494441 = 494520
107 + 494413 = 494520
113 + 494407 = 494520
137 + 494383 = 494520
139 + 494381 = 494520
151 + 494369 = 494520
167 + 494353 = 494520

Showing the first eight; more decompositions exist.
