Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648340, here are decompositions:

7 + 8648333 = 8648340
17 + 8648323 = 8648340
23 + 8648317 = 8648340
73 + 8648267 = 8648340
89 + 8648251 = 8648340
101 + 8648239 = 8648340
149 + 8648191 = 8648340
191 + 8648149 = 8648340

Showing the first eight; more decompositions exist.
