Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22688, here are decompositions:
- 19 + 22669 = 22688
- 37 + 22651 = 22688
- 67 + 22621 = 22688
- 139 + 22549 = 22688
- 157 + 22531 = 22688
- 241 + 22447 = 22688
- 307 + 22381 = 22688
- 397 + 22291 = 22688
Showing the first eight; more decompositions exist.
