Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25186, here are decompositions:
- 3 + 25183 = 25186
- 17 + 25169 = 25186
- 23 + 25163 = 25186
- 59 + 25127 = 25186
- 89 + 25097 = 25186
- 113 + 25073 = 25186
- 149 + 25037 = 25186
- 173 + 25013 = 25186
Showing the first eight; more decompositions exist.
