Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492518, here are decompositions:

7 + 492511 = 492518
31 + 492487 = 492518
97 + 492421 = 492518
109 + 492409 = 492518
199 + 492319 = 492518
457 + 492061 = 492518
541 + 491977 = 492518
619 + 491899 = 492518

Showing the first eight; more decompositions exist.
