Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665526, here are decompositions:

97 + 8665429 = 8665526
157 + 8665369 = 8665526
193 + 8665333 = 8665526
223 + 8665303 = 8665526
307 + 8665219 = 8665526
379 + 8665147 = 8665526
487 + 8665039 = 8665526
547 + 8664979 = 8665526

Showing the first eight; more decompositions exist.
