Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651492, here are decompositions:

103 + 8651389 = 8651492
139 + 8651353 = 8651492
163 + 8651329 = 8651492
181 + 8651311 = 8651492
211 + 8651281 = 8651492
313 + 8651179 = 8651492
331 + 8651161 = 8651492
349 + 8651143 = 8651492

Showing the first eight; more decompositions exist.
