Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629186, here are decompositions:

17 + 8629169 = 8629186
29 + 8629157 = 8629186
47 + 8629139 = 8629186
107 + 8629079 = 8629186
113 + 8629073 = 8629186
263 + 8628923 = 8629186
509 + 8628677 = 8629186
557 + 8628629 = 8629186

Showing the first eight; more decompositions exist.
