Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145682, here are decompositions:
- 3 + 145679 = 145682
- 79 + 145603 = 145682
- 139 + 145543 = 145682
- 151 + 145531 = 145682
- 181 + 145501 = 145682
- 211 + 145471 = 145682
- 223 + 145459 = 145682
- 241 + 145441 = 145682
Showing the first eight; more decompositions exist.
