Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25730, here are decompositions:
- 13 + 25717 = 25730
- 37 + 25693 = 25730
- 73 + 25657 = 25730
- 97 + 25633 = 25730
- 109 + 25621 = 25730
- 127 + 25603 = 25730
- 151 + 25579 = 25730
- 193 + 25537 = 25730
Showing the first eight; more decompositions exist.
