Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626488, here are decompositions:

19 + 8626469 = 8626488
29 + 8626459 = 8626488
67 + 8626421 = 8626488
71 + 8626417 = 8626488
97 + 8626391 = 8626488
139 + 8626349 = 8626488
191 + 8626297 = 8626488
239 + 8626249 = 8626488

Showing the first eight; more decompositions exist.
