Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006378, here are decompositions:

11 + 1006367 = 1006378
17 + 1006361 = 1006378
41 + 1006337 = 1006378
47 + 1006331 = 1006378
71 + 1006307 = 1006378
137 + 1006241 = 1006378
227 + 1006151 = 1006378
389 + 1005989 = 1006378

Showing the first eight; more decompositions exist.
