Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637210, here are decompositions:

7 + 8637203 = 8637210
31 + 8637179 = 8637210
47 + 8637163 = 8637210
59 + 8637151 = 8637210
79 + 8637131 = 8637210
103 + 8637107 = 8637210
107 + 8637103 = 8637210
149 + 8637061 = 8637210

Showing the first eight; more decompositions exist.
