Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17864, here are decompositions:
- 13 + 17851 = 17864
- 37 + 17827 = 17864
- 73 + 17791 = 17864
- 103 + 17761 = 17864
- 127 + 17737 = 17864
- 151 + 17713 = 17864
- 157 + 17707 = 17864
- 181 + 17683 = 17864
Showing the first eight; more decompositions exist.
