Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651382, here are decompositions:

23 + 8651359 = 8651382
29 + 8651353 = 8651382
53 + 8651329 = 8651382
59 + 8651323 = 8651382
71 + 8651311 = 8651382
101 + 8651281 = 8651382
149 + 8651233 = 8651382
151 + 8651231 = 8651382

Showing the first eight; more decompositions exist.
