Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022112, here are decompositions:
- 29 + 1022083 = 1022112
- 41 + 1022071 = 1022112
- 53 + 1022059 = 1022112
- 59 + 1022053 = 1022112
- 79 + 1022033 = 1022112
- 101 + 1022011 = 1022112
- 139 + 1021973 = 1022112
- 149 + 1021963 = 1022112
Showing the first eight; more decompositions exist.
