Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627724, here are decompositions:
- 11 + 8627713 = 8627724
- 23 + 8627701 = 8627724
- 31 + 8627693 = 8627724
- 43 + 8627681 = 8627724
- 97 + 8627627 = 8627724
- 107 + 8627617 = 8627724
- 113 + 8627611 = 8627724
- 151 + 8627573 = 8627724
Showing the first eight; more decompositions exist.
