Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003518, here are decompositions:

11 + 1003507 = 1003518
101 + 1003417 = 1003518
107 + 1003411 = 1003518
137 + 1003381 = 1003518
149 + 1003369 = 1003518
151 + 1003367 = 1003518
157 + 1003361 = 1003518
167 + 1003351 = 1003518

Showing the first eight; more decompositions exist.
