Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25278, here are decompositions:
- 17 + 25261 = 25278
- 31 + 25247 = 25278
- 41 + 25237 = 25278
- 59 + 25219 = 25278
- 89 + 25189 = 25278
- 107 + 25171 = 25278
- 109 + 25169 = 25278
- 131 + 25147 = 25278
Showing the first eight; more decompositions exist.
