Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003218, here are decompositions:

17 + 1003201 = 1003218
19 + 1003199 = 1003218
107 + 1003111 = 1003218
109 + 1003109 = 1003218
127 + 1003091 = 1003218
131 + 1003087 = 1003218
179 + 1003039 = 1003218
199 + 1003019 = 1003218

Showing the first eight; more decompositions exist.
