Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623154, here are decompositions:

13 + 8623141 = 8623154
31 + 8623123 = 8623154
73 + 8623081 = 8623154
103 + 8623051 = 8623154
151 + 8623003 = 8623154
181 + 8622973 = 8623154
271 + 8622883 = 8623154
277 + 8622877 = 8623154

Showing the first eight; more decompositions exist.
