Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51264, here are decompositions:
- 7 + 51257 = 51264
- 23 + 51241 = 51264
- 47 + 51217 = 51264
- 61 + 51203 = 51264
- 67 + 51197 = 51264
- 71 + 51193 = 51264
- 107 + 51157 = 51264
- 113 + 51151 = 51264
Showing the first eight; more decompositions exist.
