Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043280, here are decompositions:
- 59 + 1043221 = 1043280
- 67 + 1043213 = 1043280
- 71 + 1043209 = 1043280
- 79 + 1043201 = 1043280
- 89 + 1043191 = 1043280
- 97 + 1043183 = 1043280
- 103 + 1043177 = 1043280
- 107 + 1043173 = 1043280
Showing the first eight; more decompositions exist.
