Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629120, here are decompositions:

11 + 8629109 = 8629120
41 + 8629079 = 8629120
47 + 8629073 = 8629120
197 + 8628923 = 8629120
263 + 8628857 = 8629120
347 + 8628773 = 8629120
443 + 8628677 = 8629120
491 + 8628629 = 8629120

Showing the first eight; more decompositions exist.
