Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022138, here are decompositions:
- 67 + 1022071 = 1022138
- 79 + 1022059 = 1022138
- 127 + 1022011 = 1022138
- 241 + 1021897 = 1022138
- 277 + 1021861 = 1022138
- 307 + 1021831 = 1022138
- 331 + 1021807 = 1022138
- 379 + 1021759 = 1022138
Showing the first eight; more decompositions exist.
