Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629180, here are decompositions:

11 + 8629169 = 8629180
23 + 8629157 = 8629180
41 + 8629139 = 8629180
71 + 8629109 = 8629180
101 + 8629079 = 8629180
107 + 8629073 = 8629180
257 + 8628923 = 8629180
281 + 8628899 = 8629180

Showing the first eight; more decompositions exist.
