Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671178, here are decompositions:

31 + 8671147 = 8671178
79 + 8671099 = 8671178
127 + 8671051 = 8671178
181 + 8670997 = 8671178
367 + 8670811 = 8671178
499 + 8670679 = 8671178
541 + 8670637 = 8671178
619 + 8670559 = 8671178

Showing the first eight; more decompositions exist.
