Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006456, here are decompositions:

23 + 1006433 = 1006456
89 + 1006367 = 1006456
149 + 1006307 = 1006456
239 + 1006217 = 1006456
263 + 1006193 = 1006456
293 + 1006163 = 1006456
419 + 1006037 = 1006456
449 + 1006007 = 1006456

Showing the first eight; more decompositions exist.
