Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018396, here are decompositions:

59 + 1018337 = 1018396
83 + 1018313 = 1018396
149 + 1018247 = 1018396
173 + 1018223 = 1018396
179 + 1018217 = 1018396
389 + 1018007 = 1018396
443 + 1017953 = 1018396
569 + 1017827 = 1018396

Showing the first eight; more decompositions exist.
