Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25242, here are decompositions:
- 5 + 25237 = 25242
- 13 + 25229 = 25242
- 23 + 25219 = 25242
- 53 + 25189 = 25242
- 59 + 25183 = 25242
- 71 + 25171 = 25242
- 73 + 25169 = 25242
- 79 + 25163 = 25242
Showing the first eight; more decompositions exist.
