Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25170, here are decompositions:
- 7 + 25163 = 25170
- 17 + 25153 = 25170
- 23 + 25147 = 25170
- 43 + 25127 = 25170
- 53 + 25117 = 25170
- 59 + 25111 = 25170
- 73 + 25097 = 25170
- 83 + 25087 = 25170
Showing the first eight; more decompositions exist.
