Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64816, here are decompositions:
- 5 + 64811 = 64816
- 23 + 64793 = 64816
- 53 + 64763 = 64816
- 107 + 64709 = 64816
- 137 + 64679 = 64816
- 149 + 64667 = 64816
- 239 + 64577 = 64816
- 263 + 64553 = 64816
Showing the first eight; more decompositions exist.
