Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022120, here are decompositions:
- 7 + 1022113 = 1022120
- 37 + 1022083 = 1022120
- 61 + 1022059 = 1022120
- 67 + 1022053 = 1022120
- 103 + 1022017 = 1022120
- 109 + 1022011 = 1022120
- 157 + 1021963 = 1022120
- 223 + 1021897 = 1022120
Showing the first eight; more decompositions exist.
