Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022442, here are decompositions:
- 13 + 1022429 = 1022442
- 53 + 1022389 = 1022442
- 59 + 1022383 = 1022442
- 61 + 1022381 = 1022442
- 101 + 1022341 = 1022442
- 139 + 1022303 = 1022442
- 151 + 1022291 = 1022442
- 191 + 1022251 = 1022442
Showing the first eight; more decompositions exist.
