Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499172, here are decompositions:

13 + 499159 = 499172
31 + 499141 = 499172
43 + 499129 = 499172
73 + 499099 = 499172
109 + 499063 = 499172
139 + 499033 = 499172
151 + 499021 = 499172
199 + 498973 = 499172

Showing the first eight; more decompositions exist.
