Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617154, here are decompositions:

157 + 8616997 = 8617154
163 + 8616991 = 8617154
241 + 8616913 = 8617154
373 + 8616781 = 8617154
397 + 8616757 = 8617154
421 + 8616733 = 8617154
433 + 8616721 = 8617154
463 + 8616691 = 8617154

Showing the first eight; more decompositions exist.
