Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25670, here are decompositions:
- 3 + 25667 = 25670
- 13 + 25657 = 25670
- 31 + 25639 = 25670
- 37 + 25633 = 25670
- 61 + 25609 = 25670
- 67 + 25603 = 25670
- 109 + 25561 = 25670
- 199 + 25471 = 25670
Showing the first eight; more decompositions exist.
