Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629272, here are decompositions:

31 + 8629241 = 8629272
59 + 8629213 = 8629272
73 + 8629199 = 8629272
79 + 8629193 = 8629272
101 + 8629171 = 8629272
103 + 8629169 = 8629272
131 + 8629141 = 8629272
149 + 8629123 = 8629272

Showing the first eight; more decompositions exist.
