Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64858, here are decompositions:
- 5 + 64853 = 64858
- 41 + 64817 = 64858
- 47 + 64811 = 64858
- 149 + 64709 = 64858
- 179 + 64679 = 64858
- 191 + 64667 = 64858
- 197 + 64661 = 64858
- 257 + 64601 = 64858
Showing the first eight; more decompositions exist.
