Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022390, here are decompositions:
- 3 + 1022387 = 1022390
- 7 + 1022383 = 1022390
- 13 + 1022377 = 1022390
- 139 + 1022251 = 1022390
- 181 + 1022209 = 1022390
- 199 + 1022191 = 1022390
- 211 + 1022179 = 1022390
- 223 + 1022167 = 1022390
Showing the first eight; more decompositions exist.
