Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499158, here are decompositions:

7 + 499151 = 499158
17 + 499141 = 499158
19 + 499139 = 499158
29 + 499129 = 499158
31 + 499127 = 499158
41 + 499117 = 499158
59 + 499099 = 499158
131 + 499027 = 499158

Showing the first eight; more decompositions exist.
