Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629210, here are decompositions:

11 + 8629199 = 8629210
17 + 8629193 = 8629210
41 + 8629169 = 8629210
53 + 8629157 = 8629210
71 + 8629139 = 8629210
101 + 8629109 = 8629210
131 + 8629079 = 8629210
137 + 8629073 = 8629210

Showing the first eight; more decompositions exist.
