Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672488, here are decompositions:

5 + 8672483 = 8672488
17 + 8672471 = 8672488
47 + 8672441 = 8672488
59 + 8672429 = 8672488
101 + 8672387 = 8672488
107 + 8672381 = 8672488
191 + 8672297 = 8672488
281 + 8672207 = 8672488

Showing the first eight; more decompositions exist.
