Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006390, here are decompositions:

23 + 1006367 = 1006390
29 + 1006361 = 1006390
53 + 1006337 = 1006390
59 + 1006331 = 1006390
83 + 1006307 = 1006390
89 + 1006301 = 1006390
137 + 1006253 = 1006390
149 + 1006241 = 1006390

Showing the first eight; more decompositions exist.
