Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136968, here are decompositions:
- 5 + 136963 = 136968
- 17 + 136951 = 136968
- 19 + 136949 = 136968
- 71 + 136897 = 136968
- 79 + 136889 = 136968
- 89 + 136879 = 136968
- 107 + 136861 = 136968
- 109 + 136859 = 136968
Showing the first eight; more decompositions exist.
