Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25510, here are decompositions:
- 41 + 25469 = 25510
- 47 + 25463 = 25510
- 53 + 25457 = 25510
- 71 + 25439 = 25510
- 101 + 25409 = 25510
- 137 + 25373 = 25510
- 167 + 25343 = 25510
- 257 + 25253 = 25510
Showing the first eight; more decompositions exist.
