Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029220, here are decompositions:
- 11 + 1029209 = 1029220
- 29 + 1029191 = 1029220
- 41 + 1029179 = 1029220
- 53 + 1029167 = 1029220
- 107 + 1029113 = 1029220
- 197 + 1029023 = 1029220
- 239 + 1028981 = 1029220
- 251 + 1028969 = 1029220
Showing the first eight; more decompositions exist.
