Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625664, here are decompositions:
- 23 + 8625641 = 8625664
- 137 + 8625527 = 8625664
- 197 + 8625467 = 8625664
- 233 + 8625431 = 8625664
- 347 + 8625317 = 8625664
- 353 + 8625311 = 8625664
- 401 + 8625263 = 8625664
- 431 + 8625233 = 8625664
Showing the first eight; more decompositions exist.
