Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499842, here are decompositions:

23 + 499819 = 499842
41 + 499801 = 499842
61 + 499781 = 499842
103 + 499739 = 499842
113 + 499729 = 499842
131 + 499711 = 499842
149 + 499693 = 499842
151 + 499691 = 499842

Showing the first eight; more decompositions exist.
