Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020220, here are decompositions:
- 83 + 1020137 = 1020220
- 107 + 1020113 = 1020220
- 197 + 1020023 = 1020220
- 293 + 1019927 = 1020220
- 317 + 1019903 = 1020220
- 347 + 1019873 = 1020220
- 359 + 1019861 = 1020220
- 401 + 1019819 = 1020220
Showing the first eight; more decompositions exist.
