Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25630, here are decompositions:
- 29 + 25601 = 25630
- 41 + 25589 = 25630
- 47 + 25583 = 25630
- 53 + 25577 = 25630
- 89 + 25541 = 25630
- 107 + 25523 = 25630
- 167 + 25463 = 25630
- 173 + 25457 = 25630
Showing the first eight; more decompositions exist.
