Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648680, here are decompositions:

3 + 8648677 = 8648680
137 + 8648543 = 8648680
149 + 8648531 = 8648680
167 + 8648513 = 8648680
179 + 8648501 = 8648680
233 + 8648447 = 8648680
311 + 8648369 = 8648680
347 + 8648333 = 8648680

Showing the first eight; more decompositions exist.
