Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005500, here are decompositions:

7 + 1005493 = 1005500
19 + 1005481 = 1005500
43 + 1005457 = 1005500
61 + 1005439 = 1005500
73 + 1005427 = 1005500
109 + 1005391 = 1005500
127 + 1005373 = 1005500
151 + 1005349 = 1005500

Showing the first eight; more decompositions exist.
