Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25672, here are decompositions:
- 5 + 25667 = 25672
- 29 + 25643 = 25672
- 71 + 25601 = 25672
- 83 + 25589 = 25672
- 89 + 25583 = 25672
- 131 + 25541 = 25672
- 149 + 25523 = 25672
- 233 + 25439 = 25672
Showing the first eight; more decompositions exist.
