Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746440, here are decompositions:
- 13 + 8746427 = 8746440
- 41 + 8746399 = 8746440
- 61 + 8746379 = 8746440
- 71 + 8746369 = 8746440
- 83 + 8746357 = 8746440
- 89 + 8746351 = 8746440
- 137 + 8746303 = 8746440
- 139 + 8746301 = 8746440
Showing the first eight; more decompositions exist.
