Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671456, here are decompositions:

29 + 8671427 = 8671456
47 + 8671409 = 8671456
89 + 8671367 = 8671456
149 + 8671307 = 8671456
263 + 8671193 = 8671456
359 + 8671097 = 8671456
389 + 8671067 = 8671456
449 + 8671007 = 8671456

Showing the first eight; more decompositions exist.
