Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69688, here are decompositions:
- 11 + 69677 = 69688
- 131 + 69557 = 69688
- 149 + 69539 = 69688
- 191 + 69497 = 69688
- 197 + 69491 = 69688
- 257 + 69431 = 69688
- 317 + 69371 = 69688
- 347 + 69341 = 69688
Showing the first eight; more decompositions exist.
