Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25122, here are decompositions:
- 5 + 25117 = 25122
- 11 + 25111 = 25122
- 89 + 25033 = 25122
- 109 + 25013 = 25122
- 151 + 24971 = 25122
- 179 + 24943 = 25122
- 199 + 24923 = 25122
- 233 + 24889 = 25122
Showing the first eight; more decompositions exist.
