Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25570, here are decompositions:
- 29 + 25541 = 25570
- 47 + 25523 = 25570
- 101 + 25469 = 25570
- 107 + 25463 = 25570
- 113 + 25457 = 25570
- 131 + 25439 = 25570
- 179 + 25391 = 25570
- 197 + 25373 = 25570
Showing the first eight; more decompositions exist.
