Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629178, here are decompositions:

7 + 8629171 = 8629178
37 + 8629141 = 8629178
211 + 8628967 = 8629178
241 + 8628937 = 8629178
331 + 8628847 = 8629178
367 + 8628811 = 8629178
379 + 8628799 = 8629178
577 + 8628601 = 8629178

Showing the first eight; more decompositions exist.
