Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745678, here are decompositions:

41 + 8745637 = 8745678
107 + 8745571 = 8745678
127 + 8745551 = 8745678
131 + 8745547 = 8745678
229 + 8745449 = 8745678
241 + 8745437 = 8745678
311 + 8745367 = 8745678
349 + 8745329 = 8745678

Showing the first eight; more decompositions exist.
