Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038240, here are decompositions:
- 13 + 1038227 = 1038240
- 29 + 1038211 = 1038240
- 31 + 1038209 = 1038240
- 37 + 1038203 = 1038240
- 41 + 1038199 = 1038240
- 53 + 1038187 = 1038240
- 83 + 1038157 = 1038240
- 97 + 1038143 = 1038240
Showing the first eight; more decompositions exist.
