Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629238, here are decompositions:

67 + 8629171 = 8629238
97 + 8629141 = 8629238
151 + 8629087 = 8629238
229 + 8629009 = 8629238
271 + 8628967 = 8629238
349 + 8628889 = 8629238
379 + 8628859 = 8629238
439 + 8628799 = 8629238

Showing the first eight; more decompositions exist.
