Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626, here are decompositions:

3 + 8623 = 8626
17 + 8609 = 8626
29 + 8597 = 8626
53 + 8573 = 8626
83 + 8543 = 8626
89 + 8537 = 8626
113 + 8513 = 8626
179 + 8447 = 8626

Showing the first eight; more decompositions exist.
