Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651426, here are decompositions:

37 + 8651389 = 8651426
67 + 8651359 = 8651426
73 + 8651353 = 8651426
97 + 8651329 = 8651426
103 + 8651323 = 8651426
193 + 8651233 = 8651426
283 + 8651143 = 8651426
307 + 8651119 = 8651426

Showing the first eight; more decompositions exist.
