Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740512, here are decompositions:
- 19 + 8740493 = 8740512
- 59 + 8740453 = 8740512
- 83 + 8740429 = 8740512
- 101 + 8740411 = 8740512
- 139 + 8740373 = 8740512
- 181 + 8740331 = 8740512
- 191 + 8740321 = 8740512
- 211 + 8740301 = 8740512
Showing the first eight; more decompositions exist.
