Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499140, here are decompositions:

7 + 499133 = 499140
11 + 499129 = 499140
13 + 499127 = 499140
23 + 499117 = 499140
41 + 499099 = 499140
73 + 499067 = 499140
101 + 499039 = 499140
107 + 499033 = 499140

Showing the first eight; more decompositions exist.
