Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678786, here are decompositions:

3 + 8678783 = 8678786
7 + 8678779 = 8678786
13 + 8678773 = 8678786
37 + 8678749 = 8678786
73 + 8678713 = 8678786
79 + 8678707 = 8678786
199 + 8678587 = 8678786
229 + 8678557 = 8678786

Showing the first eight; more decompositions exist.
