Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25290, here are decompositions:
- 29 + 25261 = 25290
- 37 + 25253 = 25290
- 43 + 25247 = 25290
- 47 + 25243 = 25290
- 53 + 25237 = 25290
- 61 + 25229 = 25290
- 71 + 25219 = 25290
- 101 + 25189 = 25290
Showing the first eight; more decompositions exist.
