Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005406, here are decompositions:

47 + 1005359 = 1005406
89 + 1005317 = 1005406
113 + 1005293 = 1005406
137 + 1005269 = 1005406
167 + 1005239 = 1005406
197 + 1005209 = 1005406
263 + 1005143 = 1005406
419 + 1004987 = 1005406

Showing the first eight; more decompositions exist.
