Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25830, here are decompositions:
- 11 + 25819 = 25830
- 29 + 25801 = 25830
- 31 + 25799 = 25830
- 37 + 25793 = 25830
- 59 + 25771 = 25830
- 67 + 25763 = 25830
- 71 + 25759 = 25830
- 83 + 25747 = 25830
Showing the first eight; more decompositions exist.
