Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64894, here are decompositions:
- 3 + 64891 = 64894
- 17 + 64877 = 64894
- 23 + 64871 = 64894
- 41 + 64853 = 64894
- 83 + 64811 = 64894
- 101 + 64793 = 64894
- 113 + 64781 = 64894
- 131 + 64763 = 64894
Showing the first eight; more decompositions exist.
