Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25206, here are decompositions:
- 17 + 25189 = 25206
- 23 + 25183 = 25206
- 37 + 25169 = 25206
- 43 + 25163 = 25206
- 53 + 25153 = 25206
- 59 + 25147 = 25206
- 79 + 25127 = 25206
- 89 + 25117 = 25206
Showing the first eight; more decompositions exist.
