Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643264, here are decompositions:
- 41 + 8643223 = 8643264
- 53 + 8643211 = 8643264
- 67 + 8643197 = 8643264
- 83 + 8643181 = 8643264
- 127 + 8643137 = 8643264
- 131 + 8643133 = 8643264
- 173 + 8643091 = 8643264
- 181 + 8643083 = 8643264
Showing the first eight; more decompositions exist.
