Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51232, here are decompositions:
- 3 + 51229 = 51232
- 29 + 51203 = 51232
- 101 + 51131 = 51232
- 173 + 51059 = 51232
- 239 + 50993 = 51232
- 263 + 50969 = 51232
- 281 + 50951 = 51232
- 359 + 50873 = 51232
Showing the first eight; more decompositions exist.
