Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746478, here are decompositions:

19 + 8746459 = 8746478
31 + 8746447 = 8746478
79 + 8746399 = 8746478
109 + 8746369 = 8746478
127 + 8746351 = 8746478
211 + 8746267 = 8746478
241 + 8746237 = 8746478
271 + 8746207 = 8746478

Showing the first eight; more decompositions exist.
