Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005430, here are decompositions:

3 + 1005427 = 1005430
17 + 1005413 = 1005430
59 + 1005371 = 1005430
71 + 1005359 = 1005430
113 + 1005317 = 1005430
137 + 1005293 = 1005430
191 + 1005239 = 1005430
227 + 1005203 = 1005430

Showing the first eight; more decompositions exist.
