Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671478, here are decompositions:

7 + 8671471 = 8671478
31 + 8671447 = 8671478
37 + 8671441 = 8671478
97 + 8671381 = 8671478
139 + 8671339 = 8671478
157 + 8671321 = 8671478
229 + 8671249 = 8671478
331 + 8671147 = 8671478

Showing the first eight; more decompositions exist.
