Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006238, here are decompositions:

7 + 1006231 = 1006238
19 + 1006219 = 1006238
61 + 1006177 = 1006238
67 + 1006171 = 1006238
151 + 1006087 = 1006238
307 + 1005931 = 1006238
487 + 1005751 = 1006238
577 + 1005661 = 1006238

Showing the first eight; more decompositions exist.
