Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647478, here are decompositions:

19 + 8647459 = 8647478
31 + 8647447 = 8647478
61 + 8647417 = 8647478
67 + 8647411 = 8647478
109 + 8647369 = 8647478
349 + 8647129 = 8647478
457 + 8647021 = 8647478
661 + 8646817 = 8647478

Showing the first eight; more decompositions exist.
