Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672620, here are decompositions:

23 + 8672597 = 8672620
59 + 8672561 = 8672620
101 + 8672519 = 8672620
107 + 8672513 = 8672620
137 + 8672483 = 8672620
149 + 8672471 = 8672620
179 + 8672441 = 8672620
191 + 8672429 = 8672620

Showing the first eight; more decompositions exist.
