Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25222, here are decompositions:
- 3 + 25219 = 25222
- 53 + 25169 = 25222
- 59 + 25163 = 25222
- 101 + 25121 = 25222
- 149 + 25073 = 25222
- 191 + 25031 = 25222
- 233 + 24989 = 25222
- 251 + 24971 = 25222
Showing the first eight; more decompositions exist.
