Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738678, here are decompositions:

7 + 8738671 = 8738678
19 + 8738659 = 8738678
37 + 8738641 = 8738678
97 + 8738581 = 8738678
139 + 8738539 = 8738678
229 + 8738449 = 8738678
241 + 8738437 = 8738678
271 + 8738407 = 8738678

Showing the first eight; more decompositions exist.
