Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651430, here are decompositions:

31 + 8651399 = 8651430
41 + 8651389 = 8651430
71 + 8651359 = 8651430
101 + 8651329 = 8651430
107 + 8651323 = 8651430
149 + 8651281 = 8651430
163 + 8651267 = 8651430
191 + 8651239 = 8651430

Showing the first eight; more decompositions exist.
