Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678258, here are decompositions:

79 + 8678179 = 8678258
97 + 8678161 = 8678258
109 + 8678149 = 8678258
229 + 8678029 = 8678258
307 + 8677951 = 8678258
367 + 8677891 = 8678258
487 + 8677771 = 8678258
499 + 8677759 = 8678258

Showing the first eight; more decompositions exist.
