Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499830, here are decompositions:

11 + 499819 = 499830
29 + 499801 = 499830
43 + 499787 = 499830
83 + 499747 = 499830
101 + 499729 = 499830
113 + 499717 = 499830
137 + 499693 = 499830
139 + 499691 = 499830

Showing the first eight; more decompositions exist.
