Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51250, here are decompositions:
- 11 + 51239 = 51250
- 47 + 51203 = 51250
- 53 + 51197 = 51250
- 113 + 51137 = 51250
- 179 + 51071 = 51250
- 191 + 51059 = 51250
- 257 + 50993 = 51250
- 281 + 50969 = 51250
Showing the first eight; more decompositions exist.
