Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668182, here are decompositions:

31 + 8668151 = 8668182
41 + 8668141 = 8668182
71 + 8668111 = 8668182
101 + 8668081 = 8668182
109 + 8668073 = 8668182
139 + 8668043 = 8668182
151 + 8668031 = 8668182
181 + 8668001 = 8668182

Showing the first eight; more decompositions exist.
