Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25228, here are decompositions:
- 59 + 25169 = 25228
- 101 + 25127 = 25228
- 107 + 25121 = 25228
- 131 + 25097 = 25228
- 191 + 25037 = 25228
- 197 + 25031 = 25228
- 239 + 24989 = 25228
- 251 + 24977 = 25228
Showing the first eight; more decompositions exist.
