Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678478, here are decompositions:

5 + 8678473 = 8678478
31 + 8678447 = 8678478
79 + 8678399 = 8678478
139 + 8678339 = 8678478
167 + 8678311 = 8678478
241 + 8678237 = 8678478
317 + 8678161 = 8678478
331 + 8678147 = 8678478

Showing the first eight; more decompositions exist.
