Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629880, here are decompositions:
- 13 + 8629867 = 8629880
- 67 + 8629813 = 8629880
- 109 + 8629771 = 8629880
- 199 + 8629681 = 8629880
- 229 + 8629651 = 8629880
- 283 + 8629597 = 8629880
- 373 + 8629507 = 8629880
- 397 + 8629483 = 8629880
Showing the first eight; more decompositions exist.
