Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629218, here are decompositions:

5 + 8629213 = 8629218
19 + 8629199 = 8629218
47 + 8629171 = 8629218
61 + 8629157 = 8629218
79 + 8629139 = 8629218
109 + 8629109 = 8629218
131 + 8629087 = 8629218
139 + 8629079 = 8629218

Showing the first eight; more decompositions exist.
