Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029120, here are decompositions:
- 7 + 1029113 = 1029120
- 11 + 1029109 = 1029120
- 17 + 1029103 = 1029120
- 83 + 1029037 = 1029120
- 97 + 1029023 = 1029120
- 107 + 1029013 = 1029120
- 139 + 1028981 = 1029120
- 151 + 1028969 = 1029120
Showing the first eight; more decompositions exist.
