Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629130, here are decompositions:

7 + 8629123 = 8629130
43 + 8629087 = 8629130
67 + 8629063 = 8629130
127 + 8629003 = 8629130
157 + 8628973 = 8629130
163 + 8628967 = 8629130
193 + 8628937 = 8629130
241 + 8628889 = 8629130

Showing the first eight; more decompositions exist.
