Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99664, here are decompositions:
- 3 + 99661 = 99664
- 41 + 99623 = 99664
- 53 + 99611 = 99664
- 83 + 99581 = 99664
- 101 + 99563 = 99664
- 113 + 99551 = 99664
- 137 + 99527 = 99664
- 167 + 99497 = 99664
Showing the first eight; more decompositions exist.
