Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159564, here are decompositions:
- 11 + 159553 = 159564
- 23 + 159541 = 159564
- 43 + 159521 = 159564
- 61 + 159503 = 159564
- 73 + 159491 = 159564
- 101 + 159463 = 159564
- 107 + 159457 = 159564
- 127 + 159437 = 159564
Showing the first eight; more decompositions exist.
