Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651472, here are decompositions:

13 + 8651459 = 8651472
29 + 8651443 = 8651472
43 + 8651429 = 8651472
73 + 8651399 = 8651472
83 + 8651389 = 8651472
113 + 8651359 = 8651472
149 + 8651323 = 8651472
191 + 8651281 = 8651472

Showing the first eight; more decompositions exist.
