Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51946, here are decompositions:
- 5 + 51941 = 51946
- 17 + 51929 = 51946
- 47 + 51899 = 51946
- 53 + 51893 = 51946
- 107 + 51839 = 51946
- 149 + 51797 = 51946
- 179 + 51767 = 51946
- 197 + 51749 = 51946
Showing the first eight; more decompositions exist.
