Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17564, here are decompositions:
- 13 + 17551 = 17564
- 67 + 17497 = 17564
- 73 + 17491 = 17564
- 97 + 17467 = 17564
- 163 + 17401 = 17564
- 181 + 17383 = 17564
- 223 + 17341 = 17564
- 271 + 17293 = 17564
Showing the first eight; more decompositions exist.
