Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618678, here are decompositions:

97 + 8618581 = 8618678
199 + 8618479 = 8618678
349 + 8618329 = 8618678
421 + 8618257 = 8618678
457 + 8618221 = 8618678
547 + 8618131 = 8618678
571 + 8618107 = 8618678
619 + 8618059 = 8618678

Showing the first eight; more decompositions exist.
