Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742760, here are decompositions:
- 71 + 8742689 = 8742760
- 83 + 8742677 = 8742760
- 107 + 8742653 = 8742760
- 137 + 8742623 = 8742760
- 263 + 8742497 = 8742760
- 311 + 8742449 = 8742760
- 359 + 8742401 = 8742760
- 401 + 8742359 = 8742760
Showing the first eight; more decompositions exist.
