Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499572, here are decompositions:

13 + 499559 = 499572
23 + 499549 = 499572
53 + 499519 = 499572
79 + 499493 = 499572
89 + 499483 = 499572
113 + 499459 = 499572
149 + 499423 = 499572
181 + 499391 = 499572

Showing the first eight; more decompositions exist.
