Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672618, here are decompositions:

67 + 8672551 = 8672618
79 + 8672539 = 8672618
109 + 8672509 = 8672618
211 + 8672407 = 8672618
271 + 8672347 = 8672618
379 + 8672239 = 8672618
457 + 8672161 = 8672618
571 + 8672047 = 8672618

Showing the first eight; more decompositions exist.
