Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25770, here are decompositions:
- 7 + 25763 = 25770
- 11 + 25759 = 25770
- 23 + 25747 = 25770
- 29 + 25741 = 25770
- 37 + 25733 = 25770
- 53 + 25717 = 25770
- 67 + 25703 = 25770
- 97 + 25673 = 25770
Showing the first eight; more decompositions exist.
