Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498540, here are decompositions:

13 + 498527 = 498540
17 + 498523 = 498540
19 + 498521 = 498540
43 + 498497 = 498540
47 + 498493 = 498540
71 + 498469 = 498540
73 + 498467 = 498540
79 + 498461 = 498540

Showing the first eight; more decompositions exist.
