Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499578, here are decompositions:

7 + 499571 = 499578
19 + 499559 = 499578
29 + 499549 = 499578
59 + 499519 = 499578
71 + 499507 = 499578
97 + 499481 = 499578
139 + 499439 = 499578
181 + 499397 = 499578

Showing the first eight; more decompositions exist.
