Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25284, here are decompositions:
- 23 + 25261 = 25284
- 31 + 25253 = 25284
- 37 + 25247 = 25284
- 41 + 25243 = 25284
- 47 + 25237 = 25284
- 101 + 25183 = 25284
- 113 + 25171 = 25284
- 131 + 25153 = 25284
Showing the first eight; more decompositions exist.
