Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671154, here are decompositions:

3 + 8671151 = 8671154
7 + 8671147 = 8671154
97 + 8671057 = 8671154
103 + 8671051 = 8671154
157 + 8670997 = 8671154
211 + 8670943 = 8671154
487 + 8670667 = 8671154
571 + 8670583 = 8671154

Showing the first eight; more decompositions exist.
