Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012658, here are decompositions:

61 + 1012597 = 1012658
67 + 1012591 = 1012658
109 + 1012549 = 1012658
139 + 1012519 = 1012658
151 + 1012507 = 1012658
211 + 1012447 = 1012658
337 + 1012321 = 1012658
379 + 1012279 = 1012658

Showing the first eight; more decompositions exist.
