Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122928, here are decompositions:
- 7 + 122921 = 122928
- 37 + 122891 = 122928
- 41 + 122887 = 122928
- 59 + 122869 = 122928
- 61 + 122867 = 122928
- 67 + 122861 = 122928
- 79 + 122849 = 122928
- 89 + 122839 = 122928
Showing the first eight; more decompositions exist.
