Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648742, here are decompositions:

5 + 8648737 = 8648742
13 + 8648729 = 8648742
41 + 8648701 = 8648742
191 + 8648551 = 8648742
199 + 8648543 = 8648742
211 + 8648531 = 8648742
229 + 8648513 = 8648742
241 + 8648501 = 8648742

Showing the first eight; more decompositions exist.
