Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629158, here are decompositions:

17 + 8629141 = 8629158
19 + 8629139 = 8629158
71 + 8629087 = 8629158
79 + 8629079 = 8629158
149 + 8629009 = 8629158
191 + 8628967 = 8629158
269 + 8628889 = 8629158
311 + 8628847 = 8629158

Showing the first eight; more decompositions exist.
