Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25722, here are decompositions:
- 5 + 25717 = 25722
- 19 + 25703 = 25722
- 29 + 25693 = 25722
- 43 + 25679 = 25722
- 79 + 25643 = 25722
- 83 + 25639 = 25722
- 89 + 25633 = 25722
- 101 + 25621 = 25722
Showing the first eight; more decompositions exist.
