Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018320, here are decompositions:

7 + 1018313 = 1018320
11 + 1018309 = 1018320
19 + 1018301 = 1018320
29 + 1018291 = 1018320
67 + 1018253 = 1018320
73 + 1018247 = 1018320
97 + 1018223 = 1018320
103 + 1018217 = 1018320

Showing the first eight; more decompositions exist.
