Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748864, here are decompositions:
- 11 + 8748853 = 8748864
- 17 + 8748847 = 8748864
- 23 + 8748841 = 8748864
- 37 + 8748827 = 8748864
- 43 + 8748821 = 8748864
- 53 + 8748811 = 8748864
- 97 + 8748767 = 8748864
- 151 + 8748713 = 8748864
Showing the first eight; more decompositions exist.
