Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651372, here are decompositions:

13 + 8651359 = 8651372
19 + 8651353 = 8651372
43 + 8651329 = 8651372
61 + 8651311 = 8651372
139 + 8651233 = 8651372
181 + 8651191 = 8651372
193 + 8651179 = 8651372
211 + 8651161 = 8651372

Showing the first eight; more decompositions exist.
