Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672664, here are decompositions:
- 5 + 8672659 = 8672664
- 17 + 8672647 = 8672664
- 23 + 8672641 = 8672664
- 43 + 8672621 = 8672664
- 67 + 8672597 = 8672664
- 101 + 8672563 = 8672664
- 103 + 8672561 = 8672664
- 113 + 8672551 = 8672664
Showing the first eight; more decompositions exist.
