Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163894, here are decompositions:
- 11 + 163883 = 163894
- 23 + 163871 = 163894
- 41 + 163853 = 163894
- 47 + 163847 = 163894
- 53 + 163841 = 163894
- 83 + 163811 = 163894
- 113 + 163781 = 163894
- 197 + 163697 = 163894
Showing the first eight; more decompositions exist.
