Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678186, here are decompositions:

7 + 8678179 = 8678186
37 + 8678149 = 8678186
73 + 8678113 = 8678186
103 + 8678083 = 8678186
157 + 8678029 = 8678186
193 + 8677993 = 8678186
463 + 8677723 = 8678186
523 + 8677663 = 8678186

Showing the first eight; more decompositions exist.
