Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626436, here are decompositions:

19 + 8626417 = 8626436
139 + 8626297 = 8626436
193 + 8626243 = 8626436
199 + 8626237 = 8626436
277 + 8626159 = 8626436
307 + 8626129 = 8626436
337 + 8626099 = 8626436
373 + 8626063 = 8626436

Showing the first eight; more decompositions exist.
