Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498630, here are decompositions:

17 + 498613 = 498630
19 + 498611 = 498630
31 + 498599 = 498630
47 + 498583 = 498630
53 + 498577 = 498630
73 + 498557 = 498630
79 + 498551 = 498630
103 + 498527 = 498630

Showing the first eight; more decompositions exist.
