Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122886, here are decompositions:
- 17 + 122869 = 122886
- 19 + 122867 = 122886
- 37 + 122849 = 122886
- 47 + 122839 = 122886
- 53 + 122833 = 122886
- 59 + 122827 = 122886
- 67 + 122819 = 122886
- 97 + 122789 = 122886
Showing the first eight; more decompositions exist.
