Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25172, here are decompositions:
- 3 + 25169 = 25172
- 19 + 25153 = 25172
- 61 + 25111 = 25172
- 139 + 25033 = 25172
- 193 + 24979 = 25172
- 229 + 24943 = 25172
- 283 + 24889 = 25172
- 313 + 24859 = 25172
Showing the first eight; more decompositions exist.
