Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038658, here are decompositions:

29 + 1038629 = 1038658
41 + 1038617 = 1038658
59 + 1038599 = 1038658
347 + 1038311 = 1038658
389 + 1038269 = 1038658
431 + 1038227 = 1038658
449 + 1038209 = 1038658
617 + 1038041 = 1038658

Showing the first eight; more decompositions exist.
