Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498840, here are decompositions:

7 + 498833 = 498840
37 + 498803 = 498840
53 + 498787 = 498840
59 + 498781 = 498840
61 + 498779 = 498840
73 + 498767 = 498840
79 + 498761 = 498840
101 + 498739 = 498840

Showing the first eight; more decompositions exist.
