Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029730, here are decompositions:

41 + 1029689 = 1029730
83 + 1029647 = 1029730
113 + 1029617 = 1029730
137 + 1029593 = 1029730
167 + 1029563 = 1029730
197 + 1029533 = 1029730
257 + 1029473 = 1029730
263 + 1029467 = 1029730

Showing the first eight; more decompositions exist.
