Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499542, here are decompositions:

19 + 499523 = 499542
23 + 499519 = 499542
59 + 499483 = 499542
61 + 499481 = 499542
83 + 499459 = 499542
103 + 499439 = 499542
139 + 499403 = 499542
151 + 499391 = 499542

Showing the first eight; more decompositions exist.
