Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25240, here are decompositions:
- 3 + 25237 = 25240
- 11 + 25229 = 25240
- 71 + 25169 = 25240
- 113 + 25127 = 25240
- 167 + 25073 = 25240
- 227 + 25013 = 25240
- 251 + 24989 = 25240
- 263 + 24977 = 25240
Showing the first eight; more decompositions exist.
