Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492500, here are decompositions:

13 + 492487 = 492500
37 + 492463 = 492500
79 + 492421 = 492500
97 + 492403 = 492500
103 + 492397 = 492500
181 + 492319 = 492500
397 + 492103 = 492500
433 + 492067 = 492500

Showing the first eight; more decompositions exist.
